At common law, damages are a remedy in the form of a monetary award to be paid to a claimant as compensation for loss or injury. To warrant the award, the claimant must show that a breach of duty has caused foreseeable loss. To be recognised at law, the loss must involve damage to property, or mental or physical injury; pure economic loss is rarely recognised for the award of damages.
Negligence is a failure to exercise appropriate and/or ethical ruled care expected to be exercised amongst specified circumstances. The area of tort law known as negligence involves harm caused by failing to act as a form of carelessness possibly with extenuating circumstances. The core concept of negligence is that people should exercise reasonable care in their actions, by taking account of the potential harm that they might foreseeably cause to other people or property. A great example of negligence is through a civil medical negligence case - 'Wallace v Kam' - Kam said that he felt it was pointless to warn Wallace of all of the complications, so he felt that he knew that Wallace was going to continue the surgical operation regardless of the possible risks.
A plaintiff is the party who initiates a lawsuit before a court. By doing so, the plaintiff seeks a legal remedy; if this search is successful, the court will issue judgment in favor of the plaintiff and make the appropriate court order. "Plaintiff" is the term used in civil cases in most English-speaking jurisdictions, the notable exception being England and Wales, where a plaintiff has, since the introduction of the Civil Procedure Rules in 1999, been known as a "claimant", but that term also has other meanings. In criminal cases, the prosecutor brings the case against the defendant, but the key complaining party is often called the "complainant".
A tort, in common law jurisdiction, is a civil wrong that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits the tortious act. It can include intentional infliction of emotional distress, negligence, financial losses, injuries, invasion of privacy, and many other things.
Burden of proof is a legal duty that encompasses two connected but separate ideas that apply for establishing the truth of facts in a trial before tribunals in the United States: the "burden of production" and the "burden of persuasion." In a legal dispute, one party is initially presumed to be correct, while the other side bears the burden of producing evidence persuasive enough to establish the truth of facts needed to satisfy all the required legal elements of legal dispute. There are varying types of burden of persuasion commonly referred to as standards of proof, and depending on the type of case, the standard of proof will be higher or lower. Burdens of persuasion and production may be of different standards for each party, in different phases of litigation. The burden of production is a minimal burden to produce at least enough evidence for the trier of fact to consider a disputed claim. After litigants have met the burden of production, they have the burden of persuasion: that enough evidence has been presented to persuade the trier of fact that their side is correct. There are different standards of persuasiveness ranging from a preponderance of the evidence, where there is just enough evidence to tip the balance, to proof beyond a reasonable doubt, as in United States criminal courts.
A lawsuit is a proceeding by a party or parties against another in the civil court of law. The archaic term "suit in law" is found in only a small number of laws still in effect today. The term "lawsuit" is used in reference to a civil action brought in a court of law in which a plaintiff, a party who claims to have incurred loss as a result of a defendant's actions, demands a legal or equitable remedy. The defendant is required to respond to the plaintiff's complaint. If the plaintiff is successful, judgment is in the plaintiff's favor, and a variety of court orders may be issued to enforce a right, award damages, or impose a temporary or permanent injunction to prevent an act or compel an act. A declaratory judgment may be issued to prevent future legal disputes.
Collateral estoppel (CE), known in modern terminology as issue preclusion, is a common law estoppel doctrine that prevents a person from relitigating an issue. One summary is that, "once a court has decided an issue of fact or law necessary to its judgment, that decision ... preclude[s] relitigation of the issue in a suit on a different cause of action involving a party to the first case". The rationale behind issue preclusion is the prevention of legal harassment and the prevention of overuse or abuse of judicial resources.
In laws of equity, unjust enrichment occurs when one person is enriched at the expense of another in circumstances that the law sees as unjust. Where an individual is unjustly enriched, the law imposes an obligation upon the recipient to make restitution, subject to defences such as change of position. Liability for an unjust enrichment arises irrespective of wrongdoing on the part of the recipient. The concept of unjust enrichment can be traced to Roman law and the maxim that "no one should be benefited at another's expense": nemo locupletari potest aliena iactura or nemo locupletari debet cum aliena iactura.
The law of restitution is the law of gains-based recovery. It is to be contrasted with the law of compensation, which is the law of loss-based recovery. When a court orders restitution it orders the defendant to give up his/her gains to the claimant. When a court orders compensation it orders the defendant to pay the claimant for his or her loss.
In tort law, detinue is an action to recover for the wrongful taking of personal property. It is initiated by an individual who claims to have a greater right to their immediate possession than the current possessor. For an action in detinue to succeed, a claimant must first prove that he had better right to possession of the chattel than the defendant and second that the defendant refused to return the chattel once demanded by the claimant.
Bolton v. Stone[1951] AC 850, [1951] 1 All ER 1078 is a leading House of Lords case in the tort of negligence, establishing that a defendant is not negligent if the damage to the plaintiff was not a reasonably foreseeable consequence of his conduct. The plaintiff was hit by a cricket ball which had been hit out of the ground; the defendants were members of the club committee.
Assumpsit, or more fully, action in assumpsit, was a form of action at common law used to enforce what are now called obligations arising in tort and contract; and in some common law jurisdictions, unjust enrichment.
Raffles v Wichelhaus [1864] EWHC Exch J19, often called "The Peerless" case, is a leading case on mutual mistake in English contract law. The case established that when both parties to a contract are mistaken as to an essential element of the contract, the Court will attempt to find a reasonable interpretation from the context of the agreement before it will void it.
A legal case is in a general sense a dispute between opposing parties which may be resolved by a court, or by some equivalent legal process. A legal case is typically based on either civil or criminal law. In most legal cases there are one or more accusers and one or more defendants. In some instances, a legal case may occur between parties that are not in opposition, but require a legal ruling to formally establish some legal fact, such as a divorce.
A constructive trust is an equitable remedy imposed by a court to benefit a party that has been wrongfully deprived of its rights due to either a person obtaining or holding a legal property right which they should not possess due to unjust enrichment or interference, or due to a breach of fiduciary duty, which is intercausative with unjust enrichment and/or property interference. It is a type of implied trust.
Ex turpi causa non oritur actio is a legal doctrine which states that a plaintiff will be unable to pursue legal relief and damages if it arises in connection with their own tortious act. Particularly relevant in the law of contract, tort and trusts, ex turpi causa is also known as the illegality defence, since a defendant may plead that even though, for instance, he broke a contract, conducted himself negligently or broke an equitable duty, nevertheless a claimant by reason of his own illegality cannot sue. The UK Supreme Court provided a thorough reconsideration of the doctrine in 2016 in Patel v Mirza.
In English tort law, there can be no liability in negligence unless the claimant establishes both that they were owed a duty of care by the defendant, and that there has been a breach of that duty. The defendant is in breach of duty towards the claimant if their conduct fell short of the standard expected under the circumstances.
Modern libel and slander laws, as implemented in many Commonwealth nations as well as in the United States and in the Republic of Ireland, are originally descended from English defamation law. The history of defamation law in England is somewhat obscure; civil actions for damages seem to have been relatively frequent as far back as the reign of Edward I (1272–1307), though it is unknown whether any generally applicable criminal process was in place. The first fully reported case in which libel is affirmed generally to be punishable at common law was tried during the reign of James I (1603-1625). Scholars frequently attribute strict English defamation law to James I's outlawing of duelling. From that time, both the criminal and civil remedies have been found in full operation.
The English law of unjust enrichment is part of the English law of obligations, along with the law of contract, tort, and trusts. The law of unjust enrichment deals with circumstances in which one person is required to make restitution of a benefit acquired at the expense of another in circumstances which are unjust.
Jones v Dunkel is a decision of the High Court of Australia, concerning inferences that may be drawn when a civil defendant fails to give evidence.
