I NTRODUCTION
precatorem   parare ,   to   prepare   the   applicant .   Who   is   the   applicant?   In   most   instances   the   applicant   in   an   action   is   the   petitor the  petitioner , also known as, the  plaintiff
Life   in   ancient   Rome   or   in   our   era;   you   sense,   you   have   suffered   iniuria ,   harm .   How   do   you   translate   a   “sense”   of   injustice  into a legal action? 
This   chapter   looks   at   lex   Aquilia ,   specifically   procedural   aspects.   Identifying   the   petitor   is   the   first   step   in   a   long,   legal   road.  Identifying   the   defensor ,   the   defendant   is   easier   but,   finger-pointing   has   problems.   To   define   the   petitor   and   defensor ;   the  chapter looks through the lens of property and property ownership
If   the   defensor   is   a   free   person,   then   the   person   may   be   liable   for   damages.   Concerning   slaves,   a   person   held   in   bondage  cannot themselves be sued. Yet,  lex Aquilia  does permit a slave to be liable
If   the   slave   acted   without   his   master’s   knowledge,   the   petitor   can   sue   the   slave   owner.   Facing   suit,   the   slave   owner   may  either   surrender   the   slave   to   the   petitor ,   known   as   noxal   surrender   or   pay   for   the   damage.   Noxal   surrender   may   limit   the  slave owner’s cost of damages
The   issue   is   the   worth   of   the   slave   under   noxal   surrender.   If   the   slave’s   worth   is   equal   to   or   greater   than   the   cost   of   the  damage, this is a good for the  petitor
In the alternative, if the slave’s worth is lesser than the cost of the damage, this is a good for the  defensor
To   counter   the   prospect   of   a   defensor   avoiding   liability;   the   jurists   devised   theories   under   which   the   slave’s   owner   may   be  statutorily   liable.   Let   us   cite   the   circumstance,   not   a   slave   but   your   employee.   The   jurists   developed   the   theory   of   vicarious  liability  concerning acts by third parties
To   complicate   the   matter,   in   some   instances,   the   act   by   the   third   party   may   be   criminal.   In   this   instance   the   lex   Cordelia ,   criminal  suit is brought first, not to pre-judge the  lex Aquilia , a  civil  suit
Nota   bene:   Roman   jurisprudence   is   a   continuing   series,   first   commenced   in   January   2024.   The   series   assumes   you 

are   living   during   the   Principate   era.   Rome   is   at   her   apex.   You   as   a   civis ,   “citizen”;   how   do   you   navigate   through  daily lief? Along with the necessities of life, such as housing and food, how do you assert one’s legal interest? 
The   noun   erus ,   has   the   sense   of   property   owner   or   owner   or   proprietor ”.   Both   men   and   women   can   own  property.   One   of   the   benefits   of   property   ownership   is   the   enjoyment   of   said   property,   such   as   aedificare   ostium  hic, possumus nunc aditus ad atrium , “…build a door here, we can now have access to the patio” 
When   Roman   jurisprudence   speaks   of   erus ,   the   law   is   speaking   of   the   property   owner .   Matters   change   when  Emperor   Justinian,   of   the   Byzantine   Empire,   complies   Roman   obiter   dicta .   The   noun   erus   is   deleted   and   the   noun  dominus , “lord” is inserted as the  word-of-choice  for  property owner
dominus   introduces   a   ranked   social   division   regarding   property   ownership.   It   is   from   the   Byzantine   era   we   inherit  the   noun   “landlord”   and   its   derivatives,   such   as   “lord   of   the   manor”   and   “Lord”   as   a   title   (tying   land   ownership  directly to receipt of an honorific of ennoblement)
erus  is egalitarian,  dominus  is hierarchical

Likewise,   Celsus,   in   the   twenty-seventh   book   of   his  Digests,   writes   that   if   my   bees   fly   over   onto   your   (property)  and   you   burn   them   up,   some   jurists   deny   that   the   action  under   the   lex   Aquilia   lies,   among   them   is   Proculus,   on   the  theory   that   the   bees   are   not   my   property.   But   Celsus   says  that   this   is   false,   since   the   bees   are   accustomed   to   return  and   are   a   source   of   profit   for   me.   But   Proculus   was   swayed  by   the   fact   that   they   are   neither   domesticated   nor  sufficiently   enclosed.   Still,   Celsus   himself   says   that   there  is   no   difference   between   them   and   doves,   which,   if   they  escape the hand, still fly home

The   question   concerning   the   beekeeper,   does   he   retain   ownership   of   his   bees   when   they   fly   out   of   the   hive,   from   own  property to another property (to gather nectar, converted into honey)? 
Roman   jurisprudence   asserts   the   owner   of   a   wild   animal   loses   both   ownership   and   possession   when   the   animal   escapes  the owner’s control. Are bees wild animals?
In   this   circumstance   the   bees   cross   into   and   onto   another   property   for   the   express   purpose   of   gathering   nectar,   to   make  honey. Since the bees return to the owner, Proculus asserts the owner retains “ownership” of the wild animals

This action involves property ownership, the concept of  bonum fidei possessorem , the “good faith possessor”
The   bonae   fidei   possessori ,   “good   faith   possessor”   is   a   person   who   purchases   property.   The   purchaser   possesses   and  controls said property, but does  not  have  title , that is, ownership of the property 
The good faith possessor at the time of purchase did  not  realize the nature of the purchase
This action a slave possessed in good faith, is injured by another slave belonging to the good faith possessor

Celsus, a jurist
You and a colleague co-own a slave. The slave is killed by a third party. Can each owner bring a separate suit? 
Roman   jurisprudence,   specifically   lex   Aquilia ;   permits   each   co-owner,   their   own   action.   Beware ,   the   verdict   of   one   owner   in  an   action   does   not   affect   the   verdict   of   the   other   owner.   The   following   perverse   outcome   may   occur,   one   owner   may   win  with the other may loose
The   above   case   presents   one   circumstance   with   two   possible   and   opposing   outcomes.   By   the   end   of   the   Principate   era,  Roman   jurisprudence   encourages   co-owners   to   unit   and   to   present   one   action   to   assert   their   mutual   claim   against   the  defensor
All   legal   actions   have   two   aspects,   the   first   is   a   coherent   structure   of   laws   on   which   the   case   may   be   advanced   through   the  court. The second aspect, in parallel to the law; a coherent financial structure 
Nota   bene.   The   accepted   course   of   action   is   to   bring   a   civil   action   under   the   lex   Duodecim   Tabularum ,   the   “Laws 

of   the   Twelve   Tables”   also   known   as   the   “Twelve   Tables”   which   establishes   the   actionable   liability.   From   the   year  449   BCE,   henceforth,   property   law   compensation   is   cash   payment:   praemia   rei   pecuniariae ,   a   “monetary   reward  for   things”.   An   in-kind   or   similar   decision,   such   as   an   “eye-for-eye”   or   “tooth-for   tooth”   is   banned   (as   of   the   year   449 BCE. Now all successful actions, the judgement is on the basis of pecuniary compensation
To   claim   damages,   actual   damage   or   injury   must   be   presented,   that   is   damnum   iniuria   datum ,   “damage   unlawfully  inflicted”.   Roman   courts   demanded   the   petitor   must   show   actual   harm   or   injury.   If   successful,   the   claim   is   praemia  rei   pecuniariae ,   a   “monetary   reward   for   things”.   If   the   petitor   is   successful   to   this   point   in   the   proceedings,   the  actual   sum   awarded   is   based   on   the   replacement   value,   that   is;   pretium   magni   ex   prior   anno ,   the   highest   price  from   the   previous   yea r”.   The   next   issue   is   agreeing   on   the   previous   year’s   highest   pecuniary   sum.   The   iudex ,   the  “judge”   reviews   the   claim   and   counterclaim,   and   in   accordance   with   the   formula   determines   the   sum   the   defensor  owes the  petitor
The  defensor , now the  debtor , is required to pay the  debtee

wrongful   damage,   a   suit   is   granted   with   the   fiction   of

Gaius, a jurist
This   action   involves   the   civitas   Romana   peregrino ,   the   “non-citizen”   to   either   sue   or   be   sued   under     the   legal   ficta   civitate  Romana , the “fiction of Roman citizenship” 
The   obiter   dictum   permits   the   judge   to   treat   the   non-citizen   as   if   the   person   were   a   Roman   citizen.   This   comment   speaks   to  the   maturity   and   self-confidence   of   Roman   jurisprudence.   The   maturity   is   providing   guidance   to   adroitly   resolve   issues.   The  aim is to quickly allow every person to get on with their life
Roman jurisprudence extents to non-Romans legal protections 
Gaius asserts Roman law can be extended on the basis to do so is “appropriate”

It   is   agreed   that   this   action   is   granted   both   to   the   heir   and  to   other   successors.   But   this   action   will   not   be   granted  against   the   heir   or   others,   since   it   is   penal,   unless  perchance   the   heir   became   wealthier   as   a   result   of   the   loss
Footnote.

Ulpianus, a jurist
To understand this action, it is important to provide background regarding Roman inheritance law
The   heir   “succeeds”   into   the   legal   position   of   the   deceased   person,   the   assumption   is   the   heir   succeeds   to   the   property   and  the   duties   and   rights   of   the   deceased,   gratia   exempli ;   if   a   harm   is   committed   on   a   person,   that   person’s   heir   can   sue   the  defensor
Roman   inheritance   provides   some   exceptions   to   the   concept   of   succession.   Under   lex   Aquilia   the   heir   of   the   defensor   cannot  be sued. Therefore, if the  defensor  dies before the suit can be actioned,  lex Aquilian  liability is lost
The  obiter dictum  speaks to the punitive nature of  lex Aquilian  liability
You cannot inherit a punitive prerogative!

Pomponius, a jurist
The   action   looks   at   inheriting   an   estate   under   the   following   circumstance.   The   owner   of   the   estate   has   died,   but   the   heir   has  yet to receive the estate. During this time, the estate is said to “lie open”
Pomponius   states,   lex   Aquilia   statute   does   not   cite   the   name   of   the   former   owner   (now   deceased)   but   only   the   name   of   the  person who receives the property (also known as the heir)
Pomponius cites  ius postliminii , the “law of the right of recovery”
ius postliminii  refers to the legal principle that  restores  the rights of a person
Suppose   you   are   captured   by   an   enemy.   During   the   period   you   are   under   the   physical   control   of   the   enemy,   you   can   not  exercise   own   control   of   either   person   or   property.   Once   released   from   the   enemy’s   physical   control,   the   assumption   is   you  return   to   your   home.   On   return,   you   can   now   assume   control,   under   the   legal   fiction;   that   you   had   never   been   absent   in   the  first instance 
Nota   bene:   The   above   paragraph   refers   to   “control…person…”.   The   jurist   is   referring   to   the   role   of   the   paterfamilias 

(within Roman social and legal structure) 
In   the   above   action,   the   heir   may   have   been   under   the   circumstance   he   was   not   able   to   assume   his   inheritance.   But,   under  ius   postliminii   the   heir   assumes   his   inheritance   under   the   legal   fiction,   the   period   of   non-assumption   is   pushed   aside   as   if   it  had never existed. He  recovers  his property

If   a   slave   in   an   inheritance   is   slain,   a   question   arises   as   to  who   has   the   Aquilian   action,   since   there   is   no   owner   of   this  slave.   Celsus   says   that   the   statute   wanted   the   owner’s  losses   to   be   compensated,   therefore   the   inheritance   is  regarded   as   the   owner.   Hence   the   heir   can   sue   when   the  inheritance   is   accepted.   If   a   legated   slave   was   slain   after  the   inheritance   is   accepted,   (a   jurist   says)   that   the   action  under   the   lex   Aquilia   goes   to   the   legatee   unless   he  accepted   the   legacy   (only)   after   the   slave’s   death,   but   if   he  rejected   it   Julian   says   the   logical   consequence   is   that   it  goes to the heir

Once   the   heir   accepts   the   inheritance,   distribution   is   in   accordance   with   the   legator’s   stipulation.   Julian,   another   leading  jurist, is cited; the property, the slave, is assigned to the heir

But   also   if   the   owner   of   the   property   wounds   or   slays   slave   in   whom   I   have   a   usufruct,   I   should   be   granted   an  action   against   him,   on   the   model   of   the   lex   Aquilia,   in  proportion   to   the   usufruct,   (but)   so   that   the   part   of   the   year  is also evaluated in which I did not yet have the usufruct
usus   fructus ,   “usufruct   of   property”   is   a   right   to   enjoy   property   and   its   profit   therefrom   for   a   term   not   to   exceed   the   lifetime  of   the   beneficiary.   Usually,   the   usufruct   is   a   legacy   in   a   will,   the   testator   designates   one   person   the   heir   but   grants   the  usufruct to another person to receive the property therefrom
An   example   of   usufructory   circumstance   where   the   property   owner   is   not   an   heir;   the   usufructee   is   the   owner   of   an   apple  orchard,   but;   due   to   circumstance   of   physical   incapacity   or   lives   elsewhere   or   is   absent   on   military   service;   the   usufructor    maintains the orchard and receives the profit (the apples)
The   relationship   is   mutually   advantageous.   The   usufructor   “maintains   the   property   and   receives   the   profit”.   This   means   he  has own interest in managing the property to receive the profit. Failure to manage the property means less profit 
Nota   bene:   The   obiter   dicta   of   the   two   cases   are   “confused”.   The   confusion   may   have   originated   at   the   time   of 

compilation 
Case   LXXVI,   Julian   suggests   a   statutory   action   under   lex   Aquilia.   Paul   LXXVII,   suggests   an   analogous   action,   an   utile  iudicium” 
Case   LXXVII,   cites   the   circumstance   of   the   property   owner   slaying   a   slave.   On   slaying   the   slave,   the   owner   reduces   the   value  of own property, therefore reduces the value of the property, the usufructor sues the usufructee

If   a   slave   was   given   as   a   pledge   (pignus)   and   then   slain,   the  debtor   has   the   action.   But   question   is   raised   whether   an  analogous   action   (actio   utilis)   should   also   be   granted   to   the  creditor,   since   he   may   have   an   interest   because   the   debtor  is   insolvent   or   his   suit   on   the   debt   is   barred   by   lapse   of  time.   But   here   it   is   unfair   that   he   (the   defendant)   be   liable   to  both   the   debtor   and   creditor.   Unless   one   thinks   that   the  debtor   will   suffer   no   wrong   in   this   matter,   since   he   is  advantaged   as   regards   the   amount   of   the   debt   and   will  recover   the   surplus   from   him,   or   that   the   debtor   should  from   the   start   be   granted   an   action   for   the   surplus   over   and  above   the   debt.   And   so   in   these   cases   where   the   action  should   be   granted   to   the   creditor   because   of   the   debtor’s  insolvency   or   because   action   is   barred,   the   creditor   will  have   an   Aquilian   action   up   to   the   amount   of   the   debt   so   as  to   benefit   the   debtor,   but   the   debtor   has   the   Aquilian   action  for the excess over the debt
Who has the interest in the slain slave, pledged against a debt? The answer is the debtor
The jurist then asks the question, what interest does the creditor have against the insolvent or time-barred debtor? 
The   jurist   then   raises   the   possibility   the   defendant   may   be   liable   to   both   the   debtor   and   creditor.   Assume   the   slave   at   death  was worth 10,000, the debtor’s interest is 7,000; the creditor can sue for 3,000
Marcellus,   a   jurist   not   cited   in   the   case;   speaks   of   a   debtor   who   gave   own   slave   as   a   pledge,   but   plucks   out   one   of   the   slave’s  eyes, thus reducing the slave’s value. The case allowed the creditor to sue the debtor 
In   the   case   of   the   insolvent   debtor,   the   action   benefits   the   creditor,   since   the   creditor   has   preferred   status   against   the  debtor’s other creditors

Ulpianus, a jurist
bonae   fidei   possessori ,   a   “good   faith   possessor”   holds   property   that   belongs   to   another   person,   the   owner   may   reclaim   the  property   at   any   time.   Depending   on   the   property   possessed,   there   may   be   accrual   of   expenses.   If   “yes”,   the   good   faith  possessor may retain the property if the owner does  not  compensate the possessor
The   chief   distinction   between   property   held   under   usufruct   and   a   good   faith   possessor,   under   the   former;   the   owner   retains  legal   possession   and   control   of   the   property.   If   there   are   expenses   the   usufructor   cannot   keep   the   property   but   may   sue   for  expenses
Ulpianus,   in   his   obiter   dictum ;   thought   the   property,   a   slave;   is   slain   by   the   owner,   the   good   faith   possessor   may   sue   the  owner under an  in factum  action for expenses incurred
Even   if   the   good   faith   possessor   can   sue   under   lex   Aquilia ,   statute   law;   the   better   course   of   action     anticipating   success   –  is  in factum

It   is   beyond   doubt   that   those   who   undertake   to   guard  something   (for   pay)   or   who   receive   its   (gratuitous)   use   are  not   liable   for   wrongful   loss   inflicted   by   a   third   party.   For  what   care   or   diligence   of   ours   can   prevent   someone   from  inflicting wrongful loss on us?

Julian, a jurist
Roman   jurisprudence,   a   person   who   receives   the   gratuitous   use   of   an   object   or   who   is   hired   to   guard   it,   is   held   to   a   very  high standard of care called  custodia, a “ guard
The   custodia   may   be   liable   if   the   object   is   lost   or   damaged   due   to   carelessness   or   negligence;   except   in   the   circumstance  of  vis maior , “irresistible force”. An example of  vis maior  is “forceable theft”
Case   LXXX,   Ulpianus   citing   Iulianus   says   the   custodia   is   not   liable.   While   the   custodia   is   held   liable   for   things   in   his   care,  he is not liable for third party action of torn clothing. If the clothing is torn, sue the owner not the  custodia
Case LXXXI, Iulianus supports Ulpianus, a  custodia  is not liable for third party loss
C ONCLUSION
Case   LXIX,   A   Neighbour   Destroys   Bees   establishes   two   fundamental   points   of   property   ownership:   possession   and   control.  The   case   also   identifies   the   petitor   and   defensor   in   an   action.   Though   bees   fly   to   neighbouring   properties   to   gather   nectar,  the   person   who   has   possession   of   the   beehive,   the   domicile   of   a   honeybee;   has   “possession”   and   “control”   of   his   property  that is the honeybee, though a wild animal, returns to the beehive
In   quick   order   Case   LXXI   examines   co-ownership   of   property,   commencing   with   either   single   or   joint   action   and   the   award  of   damages   based   on   per   centage   of   ownership.   Case   LXXII   considers   suing   or   being   sued   by   a   civitas   Romana   peregrino non-Roman citizen  through the legal device of  ficta civitate Romana , the  fiction of Roman citizenship
Case   LXXIII   examines,   within   the   context   of   an   inheritance,   the   issue   of:   does   inheritor   have   the   privilege   to   sue,   “yes”?  There   is   no   reciprocal   privilege   for   the   defensor .   Case   LXXIV   establishes   the   inheritor   who   may   not   be   able   to   assume   the  inheritance, the privilege of property owners exists under  postiminii , the law of the right of recovery
Finally,   issues   of   petitor   and   defensor ,   of   property   “possession”   and   “control”   are   discussed   concerning   the   pledge ,   the  good faith possessor , the  borrower , and the  custodian
