9. Obligations: Common Principles and Obligations Arising from Contracts Flashcards
(181 cards)
Obligations in General
> J. 3. 13pr: “An obligation is a legal tie which binds us to the necessity of making some performance in accordance with the laws of our state.”
Legal tie = vinculum iuris.
Situations where a person has incurred a personal liability for which he is answerable at law.
Rights and duties in personam - Paul: “binds another person to give, do, or perform something for us.”
How were contracts incurred?
-contracts made by parties
-delicts committed by one against another.
Obligation: duty arose on the one incurring the obligation and the other had a right to enforce that duty by legal action (an actio in personam) - award for damages.
So for P, could be seen as an asset, a res incorporeales so G put in law of things.
Classification of obligations
- Ius civile vs. ius honorarium (and later prob mid 2nd C AD - natural obligations added too).
- Unilateral and bilateral.
- Stricti iuris and bonae fidei.
>Unilateral - stricti iuris - delict.
>Bilateral - bonae fidei - contract.
Natural Obligations
> Not legally enforceable agreements but could have legal consequences.
Slave and master, PF and his family.
Source of Obligation
> Most important classification of obligations was according to its source (causa).
Gaius Golden Words - delict, contract, ‘special right’.
J. 3. 13. 2: 4 - contract, delict, quasi-contract, quasi-delict.
Could Q-D & Q-C equal special right? Unlikely though as G regards obligations as arising from ius civile and Q-D is a product of praetorian intervention.
Justinian’s classification of obligations
> Obligations arose from 4 sources:
- Contract
- Quasi-contract
- Delict
- Quasi-delict
Justinian’s classification of obligations - contracts
> Contracts = agreement enforceable at law:
1. Consensual = informal agreement leads to obligation.
2. Verbis = Obligation made by saying set words.
3. Re = obligation made through delivery of a thing, e.g. loan, deposit.
4. Litteris = originally made by HoF writing in a ledger but by J, it was simply acknowledgement of a fictitious loan.
J’s 4-fold classification is insufficient as it doesn’t take into account pacts and innominate contracts:
-doesn’t want to disturb symmetry?
-Zimmerman: J influenced by symbolism of numbers, 4 relates to secular structure of world.
Justinian’s classification of obligations - quasi-contract
> Situations not strictly contractual, but liability in personam still arose.
No unifying link.
E.g. negotiorum gestio = performing services for another person without their consent.
E.g. unjust enrichment.
Justinian’s classification of obligations - delict
> Obligations arising form the commission of civil wrongs.
>Delicts had penal consequences.
Justinian’s classification of obligations - quasi-delict
> Untify and ununified category.
Common Features of Roman Contracts
> RL of contracts = law of discrete transactions with no unifying principle except necessity of an agreement.
Early Rome, law revolved largely around a single contract - stipulatio.
But later the law of contract became the law of contracts.
Stricti iuris came from ius civile (formula of action empowered the iudex to apply his equitable discretion to the facts of the case.)
Bonae fidei introduced through ius honorarium.
Stricti iuris contracts, e.g. stipulatio, required strict observance of outward formalities of the act.
Number of common features but no ‘general principle of contract.’
Consensus
> Agreement was essential especially in consensual contracts.
Genuine meeting of minds = consensus ad idem at moment contract made.
Unresolved ambiguity in the language could render the contract void however, the judge tried to resolve through interpreting the conduct and custom.
As last resort, ambiguities were construed against the party regarded as having the principal role in the formulation of the particular term in the question.
Paul, Sabinus, book 5: “vendor could have declared his will more explicitly.” D. 18. 1. 21.
Even if language was unambiguous, consensus may still be lacking due to mistake, duress or fraud.
Mistake - general
> In RL, need for strict consensus led to wider role for rules on mistake than in CL.
Fatal mistakes:
1. Mistaken transaction (error in negotio)
2. Mistaken subject matter (error in corpore)
3. Mistaken identity (error in persona)
4. Mistake in quality of subject matter (error in substantia).
Mistake would make the contract void, but there could still be legal action, e.g. if buyer recovered sale price, the vendor could bring an action to recover the good.
Mistake - mistaken transaction
> Error in negotio.
Parties mistaken about type of transaction intended.
E.g. one thought loan and the other sale.
Mistake - mistaken subject matter
> Error in corpore.
Mistake over identity of the contract’s central object.
Contract still valid if mistake was about identity of accessory thing.
Mistake - mistaken identity
> Error in persona.
Mistake over identity of other party.
Only if identity of other party was relevant to the contract.
Mistake - mistake in quality
> Error in substantia.
Only post-classical.
Mistake regarding quality of subject matter of the contract.
Could only invalidate BF contract, not SI.
Had to be a fundamental mistake.
Fundamental = i.e. something sold from different category to that which the buyer presumed.
Fundamental - unclear, interpolation?
Duress
> A contract was made under duress if the party had been threatened with ‘serious evil’ unless he consented to the contract.
Effect of duress varied due to contract type:
1. Stricti iuris under duress:
-was still valid in archaic and pre-classical period, but one would hope that the praetor prevents agreement’s enforcement or grants restitutio.
-late Republic, the exceptio metus (‘the defence of duress’) was allowed to prevent enforcement and an actio metus was allowed for those who suffered loss due to duress.
2. BF contract wasn’t necessarily invalid, but judge took into account.
A contract made through force, no matter the type, was invalid.
Fraud
> Ulpian, Edict, book 11: “every kind of cunning, trickery or contrivance practiced in order to cheat, trick or deceive another.” D.4.3.1.2.
SI contracts = no defence nor remedy until into of exceptio doli (for defence) and actio doli in the late Republic.
If fraud induced a mistake, which would have invalidated the contract, then regarded as mistake rather than fraud.
What turned an agreement into a contract?
> Contracts only arose from agreements which were actionable at law.
Actionable if there was a causa.
Cause = ground, reason, cause.
Causa
> Sometimes, the form of the agreement constituted the causa, e.g. written ledger in contract litteris, or delivery of the thing in contracts re.
But what was the causa when mere agreement sufficed?
Socio-economic conditions of Rome: consensual contracts established in 3rd C BC as economic necessity to recognise causa so legally actionable.
Could also mean motive for transaction or interdependence of promises.
Possible that causa wasn’t essential to every Roman contracts and that modern scholars have exaggerated.
Capacity
> Not valid unless both parties had the capacity to make the contract.
Illegality and immorality
> Ulpian, Sabinus, book 42: “immoral stipulations have no validity.” D. 45.1.26.
Agreement to perform an illegal or immoral act was a nullity.
Early Emp., statutes could impose a sanction of invalidity, but before in Republic, legislation didn’t necessarily invalidate transactions made in breach of statutory provisions, e.g. lex Cincia on gifts.
Whether transactions were contra bonos mores (immoral) was determined by contemporary standards of morality.
Unclear whether religious and philosophical moral doctrines influenced this concept of good morals.
Impossibility - general
> Celsus, Digest, book 8: “There is no obligation to do anything which is impossible.”
2 types:
1. Initial impossibility
2. Supervening impossibility
Impossibility - initial impossibility
> Agreement was void is agreement was already impossible to perform at the time it was made:
- objective
- impossible in nature of the things for anyone not just the party involved
- could be physically or legally impossible.
