Essays on jurisprudence from an English law perspective
A B C D E F G H I J K L M N O P Q R S T U V
Patrick Bracher in Johannesburg started compiling this A to Z of Latin terms when RE: was founded in 2011. As 2020 comes to an end, so does he. His monumental task is done.
ad hoc
This particular purpose. The more casual use as ‘impromptu’ or ‘without forethought’ is not strictly correct but is common.
ad idem
Agreement.
a fortiori
The Cambridge Guide to English Usage defines this perfectly: “This elliptical phrase means roughly by way of something stronger. Far from being an oblique reference to fetching the whisky, it’s used in formal discussion to mean ‘with yet stronger reason’ and to introduce a second point which the speaker or writer feels will clinch the argument.”
a priori
This phrase concerns reasoning. It means from what went before to suggest cause and effect. As the cause relied on is often an assumption, it can have negative connotations.
amicus curiae
Friend of the court. With the growing number of human rights cases, a friend of the court can play an important role in giving the courts a broader picture than the immediate, adversarial litigants might offer.
animus
Intention. In the legal context, animus normally implies hostile intent to injure or insult.
audi alteram partem
Espoused by Augustine, the requirement to hear the other side is an important principle of natural justice in dispute resolution and administrative law.
annus mirabilis
Year of wonder, year of marvels. A good note to end on for some.
blandae mendacia linguae
The lies of a flattering tongue: a warning against silver-tongued advocacy.
bona fide(s)
Good faith. Sometimes translated as ‘in good faith’ (an offer in good faith).
bona vacantia
Goods without an owner which then belong to the State. The assets of a corporation wrongly deregistered may revert to the State until the company is re-registered.
brutum fulmen
An innocuous thunderbolt, used by (the Roman natural philosopher) Pliny the Elder in the sense of an empty threat.
cadit quaestio
The question falls. The argument has reached a point where there is nothing more to be said. The question is answered.
caveat emptor
Let the buyer beware. This phrase has less immediacy in this age of consumer protection legislation.
compos mentis
Of sound mind. (As opposed to compost mentis.)
contra bonos mores
Harmful to the moral welfare of society and therefore unenforceable in a court (such as an agreement to commit a crime).
cuius est solum, ejus est usque ad caelum et usque ad infero
Whoever owns the land, owns it up to the heavens and down to the core of the earth. In an age where mineral rights are often owned by, and airspace controlled by, the State, this maxim has become an over-simplification.
contra proferentem
Literally, ‘against the proferring party’ where ambiguity or uncertainty in a document is construed against the party responsible for drafting it.
damnum sine injuria esse potest
There can be physical injury without legal liability—which is why players cannot sue for ordinary rugby injuries (other than a defence of insanity).
doli incapax
Legally incapable of committing a wrong. There is an extraordinary presumption that children under a certain age (seven in some parts of the world, ten in others) cannot act maliciously.
dona clandestina sunt semper suspiciosa
Secret gifts are always suspicious. The reason for the UK Bribery Act.
ejusdem generis
Of the same type. Where particular words describe a particular category of thing or person, general words that follow are interpreted to include only things of the same class. The birds-of-a-feather principle. So ‘oranges, etc’ and ‘oranges, peaches, etc’ mean all fruit but ‘oranges, lemons, grapefruit, etc’ probably means all citrus fruit.
e pluribus unum
Out of many, one, or, simply, united, which explains why it is the motto on the great seal, designed in the eighteenth century for the United States. Clear light from the full spectrum of colours is a more poetic example.
ex abundanti cautela
From an abundance of care. This is the Latin belt-and-braces principle. When President Obama had his oath of office repeated following his Inauguration, this was done ex abundanti cautela.
ex contractu
Arising from contract. It is usually a judicial policy decision whether someone who breaches a contract can also be sued in tort (delict) for any harm done (which is, for instance, usually the case in medical negligence actions).
ex gratia
As an act of grace or as a favour. Remember, if you pay a claim ex gratia your goodness may not be rewarded because, in the absence of a legal liability to pay, you may not be able to recover your outlay from a third party.
ex officio
By virtue of the office or status held, to be given some particular position or privilege. For example, the managing director is ex officio chair of the board.
ex parte
In relation to a court application, by one party only without notice to any other party. It is sometimes used to describe the parties to a case where one represents the interests of another. For example, R v Committee of Lloyd’s, ex parte Posgate 1983. It is not a hangover.
ex tempore
On the spur of the moment. Can be described as an off-the-cuff speech, which often proves the rule that an unprepared speech is not worth the paper it is written on.
ex turpi causa non oritur action
A claim will not be countenanced by a court if the party bringing the claim is guilty of moral turpitude or illegal conduct. It is similar to the requirement of having to come to court with clean hands.
ex nihilo nihil fit
The ancient Roman version—re The Sound of Music—of the song ‘Nothing comes from nothing’.
ex silentio
A conclusion drawn from the fact that nothing was said or written. Rather like the undisguised elephant in the room.
fac simile
Literally, ‘make the like’. A facsimile. But fax in Latin is a torch.
fiat justitia
‘Let justice be done.’ Sometimes the words ruat caelum, ‘though the heavens fall’, are added.
flagrante delicto
Caught in the act of committing the crime, from flagro, ‘to burn with passion’, giving some clue to its common use.
forum conveniens
More correctly, the ‘appropriate’ forum rather than ‘the convenient forum’; the jurisdiction where the interests of justice will best be served.
functus officio
Having performed his or her office. With the official job done, a person is no longer vested with the powers of office. A judge is functus officio after delivering a judgment and cannot change the decision.
generalia
General words or principles. Often used in generalia specialibus non derogant, a guide to interpretation that general provisions don’t prevail over special provisions.
grammatica falsa non vitiat chartam
‘False grammar does not vitiate a deed’, which is a good thing for many lawyers.
gravitas
A serious or solemn demeanour, once prized in judges.
habeas corpus
Have [produce] the body. A long-standing human rights law requiring that arrested persons be brought before a court straight away to determine if the detention is lawful.
habendum et tenendum
To have and to hold. The opposite of having your cake and eating it.
hostis humani generis
Enemy of mankind subject to capture by all states (e.g. a pirate). Nowadays, sought by Interpol.
ignorantia juris non excusat
This well-known phrase needs little introduction: ignorance of the law is no excuse.
imperitia culpae adnumeratur
Lack of skill is blameworthy. If an activity needs particular skills (such as those of a surgeon), it is negligent to act without applying those skills.
in aeternum
For eternity. You could also say, For ever. To the ends of time. To infinity and beyond.
in camera / in curia
In court proceedings: in private; or, in open court.
in extensor
Stated at full length. The sign of a bore.
in extremis
At the point of death.
in forma pauperis
Destitute and therefore not required to pay the costs in a law suit.
in gremio legis
In the lap of the law. In open and democratic societies everyone should be under the protection of the law.
in judicando esto pupillis misericors
In judging be merciful to minors. A worthy sentiment on the statue of St Yves in Brittany (from the Vulgate).
in limine
On the threshold. Usually a preliminary point taken in court in the hope of defeating the whole action.
in loco parentis
A person in the place of a parent and therefore having similar obligations to care for the child—as, for example, a playschool.
in pari delicto
Equally corrupt. When two parties to a deal are equally villainous, the court will not come to either party’s aid.
in pari materia
Of like material or substance, or materially similar, showing nicely the origin of the word ‘material’ in both senses.
in prompt
In readiness. The Latin origin of ‘impromptu’.
in re
In the matter of. Also ‘in re:’, meaning in a great magazine.
in specie
In tangible form. Repayment of a debt paid in gold coins is repaid in specie in gold coins.
in terrorem
By way of a threat. As in an excessive penalty for breach.
intra vires
Validly done within one’s powers to act.
in vacuo
In a vacuum. Without any context.
in vino veritas
In wine there is truth—alcohol being a later-to- be-regretted truth serum.
infinitum jure reprobatur
The law abhors endless litigation (wishful thinking).
injuria
Injury. Usually used in relation to reputation rather than bodily injury.
ipse dixit
In their own words. An uncorroborated statement, not be confused with ipsissima verba, meaning ‘the exact words used’.
ipso facto
By the very fact itself. ‘Therefore’ will usually do.
ipso jure
By the operation of law.
ius
A right or a legal system. Better not spelt using a ‘j’ to avoid confusion with ‘juice’.
ius civile
The civil law. In Roman times this was the law of Rome as opposed to the jus gentium, which were laws of universal application.
The letter ‘j’ is a latecomer to the alphabet and was not used in Roman Latin, where an ‘i’ was invariably used (and still is by the purists).
jacta alea est
The die is cast. Attributed to Julius Caesar when he crossed the Rubicon to challenge the Roman authorities and started the civil war.
justa causa
A just cause or lawful ground. Used in Roman law instead of the need for a consideration as the basis for an agreement.
justus error
A reasonable or excusable error. Sometimes excusing liability.
Although there was a ‘k’ in Latin, the ‘c’ was preferred and ‘k’ is hardly ever used.
laesa majestas
Injured majesty. The crime of laesae majestatis is the crime of high treason.
legem brevem esse oportet
A law should be brief. A rare achievement.
legum baccalaureus, legum majister
LLB and LLM. Well-known law degrees.
lex fori
Law of the forum. The law of the court in which the action is heard.
lex loci
The law of the place. The law where the act occurred.
lex non cogit ad impossibilia
The law does not compel the impossible. As in failing to report an accident when unconscious.

locus classicus
A classic place or source. It refers to the leading authority on a point.
locus standi

The great charter of liberty and political rights of 1215, much written about in 2015.
mala fide

mala grammatica non vitiat chartam

mandamus
We command. Usually a court order obliging the respondent to do something.
mea culpa
My fault! Your insurers won‘t thank you for saying so.
mendacem memorem esse oportet
A liar should have a good memory. The first thing a witness being cross-examined should remember.
mirabile dictu
Amazingly. Or ‘wonderful to relate‘. Often used ironically.
modus operandi
Manner of working. Sometimes used as evidence of a pattern of criminal behaviour to prove a crime.
modus vivendi
Way of living. ‘Lifestyle’ being the modern equivalent.
moratorium
From the Latin mora for ‘delay’. A temporary suspension of an obligation to do something or pay a debt.

Necessity has no law. Acting from necessity can be a defence to allegations of wrongful conduct.
nemine contradicente
Nobody dissenting. As in the tacit unanimous approval of a meeting. Usually written as nem. con.
nemo judex in causa sua
Nobody should judge in their own cause. No one should sit in judgment in a matter in which they have a personal involvement or interest which is a ground for asking for recusal.
ne sutor ultra crepidam
Let the cobbler not venture beyond his sandal. Stick to what you know.
nolle prosequi
No wish to proceed. It indicates that the prosecution authority will not be proceeding with a criminal matter. I knew a deputy attorney general years ago who, when he got too busy, threw all the files up in the air and those that landed on the floor were stamped nolle prosequi.
non compos mentis
No control of one’s mind. A defence to an accusation of wrongfulness.

noscitur a sociis

novus actus interveniens
A new intervening act or cause. A second act which breaks the chain of causation so that the original wrongdoer is not responsible for the final adverse outcome.
noxiae poena par esto
Let the punishment fit the crime (Cicero). A principle of sentencing.
nulla poena sine lege

obiter dictum

obscurum per obscurius
Explaining something obscure by what is more obscure. Often the case when lawyers attempt to argue by analogy.
omnia praesumuntur rite esse acta

pari passu
With equal pace or force. Particularly when balancing the rights of two or more parties or assets in a transaction.

reductio ad absurdum
Reduced to absurdity. A line of argument used to show that the opposition’s proposed reasoning leads to a nonsensical conclusion. The argument is often as nonsensical.
res inter alios acta
A transaction between persons which cannot be relied on by a third party. Car insurance, for example, cannot benefit a third party causing the damage.

sine die
Without a day. An adjournment of court case or meeting, etc to an unspecified date, which often leads to delays.
stare decisis
Stand by decided matters. Past judgments are binding unless clearly wrong or overtaken. The recent UK Supreme Court Brexit decision relied on case law going back to 1611.
