In law, the substantial certainty doctrine is the assumption of intent even if the actor did not intend the result, but knew with substantial certainty the effect would occur as a result of his action. [1] The doctrine can be used by courts as a test to determine whether or not a defendant committed a tort. For example, in Garratt v. Dailey (1955), the Washington Supreme Court remanded a case back to the lower courts to determine whether or not the five year-old defendant "knew with substantial certainty that the plaintiff would attempt to sit down where the chair which he moved had been." [2]
In law, a proximate cause is an event sufficiently related to an injury that the courts deem the event to be the cause of that injury. There are two types of causation in the law: cause-in-fact, and proximate cause. Cause-in-fact is determined by the "but for" test: But for the action, the result would not have happened. The action is a necessary condition, but may not be a sufficient condition, for the resulting injury. A few circumstances exist where the but for test is ineffective. Since but-for causation is very easy to show, a second test is used to determine if an action is close enough to a harm in a "chain of events" to be legally valid. This test is called proximate cause. Proximate cause is a key principle of Insurance and is concerned with how the loss or damage actually occurred. There are several competing theories of proximate cause. For an act to be deemed to cause a harm, both tests must be met; proximate cause is a legal limitation on cause-in-fact.
Mens rea is the mental element of a person's intention to commit a crime; or knowledge that one's action or lack of action would cause a crime to be committed. It is a necessary element of many crimes.
Burden of proof is a legal duty that encompasses two connected but separate ideas that 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.
Trespass is an area of criminal law or tort law broadly divided into three groups: trespass to the person, trespass to chattels and trespass to land.
Estoppel is a judicial device in common law legal systems whereby a court may prevent or "estop" a person from making assertions or from going back on his or her word; the person being sanctioned is "estopped". Estoppel may prevent someone from bringing a particular claim. Legal doctrines of estoppel are based in both common law and equity. It is also a concept in international law.
This article addresses torts in United States law. As such, it covers primarily common law. Moreover, it provides general rules, as individual states all have separate civil codes. There are three general categories of torts: intentional torts, negligence, and strict liability torts.
Beyond a reasonable doubt is a legal standard of proof required to validate a criminal conviction in most adversarial legal systems. It is a higher standard of proof than the balance of probabilities and is usually therefore reserved for criminal matters where what is at stake is considered more serious and therefore deserving of a higher threshold.
Forum non conveniens (FNC) is a mostly common law legal doctrine whereby a court "acknowledges that another forum or court is more appropriate and sends the case to such a forum. A change of venue, where another venue is more appropriate to adjudicate a matter, such as the jurisdiction within which an accident occurred and where all the witnesses reside."
In English criminal law, public nuisance is a class of common law offence in which the injury, loss, or damage is suffered by the public, in general, rather than an individual, in particular.
Under the Noerr–Pennington doctrine, private entities are immune from liability under the antitrust laws for attempts to influence the passage or enforcement of laws, even if the laws they advocate for would have anticompetitive effects. The doctrine is grounded in the First Amendment protection of political speech, and "upon a recognition that the antitrust laws, 'tailored as they are for the business world, are not at all appropriate for application in the political arena.'"
Garratt v. Dailey, 46 Wash. 2d 197, 279 P.2d 1091 is a famous American tort law case that illustrates the principle of "intent" for intentional torts.
An intentional tort is a category of torts that describes a civil wrong resulting from an intentional act on the part of the tortfeasor. The term negligence, on the other hand, pertains to a tort that simply results from the failure of the tortfeasor to take sufficient care in fulfilling a duty owed, while strict liability torts refers to situations where a party is liable for injuries no matter what precautions were taken.
Causation is the "causal relationship between the defendant's conduct and end result". In other words, causation provides a means of connecting conduct with a resulting effect, typically an injury. In criminal law, it is defined as the actus reus from which the specific injury or other effect arose and is combined with mens rea to comprise the elements of guilt. Causation only applies where a result has been achieved and therefore is immaterial with regard to inchoate offenses.
In English criminal law, intention is one of the types of mens rea that, when accompanied by an actus reus, constitutes a crime.
Blockburger v. United States, 284 U.S. 299 (1932), was a case in which the Supreme Court of the United States set an important standard to prevent double jeopardy.
Substantial similarity, in US copyright law, is the standard used to determine whether a defendant has infringed the reproduction right of a copyright. The standard arises out of the recognition that the exclusive right to make copies of a work would be meaningless if copyright infringement were limited to making only exact and complete reproductions of a work. Many courts also use "substantial similarity" in place of "probative" or "striking similarity" to describe the level of similarity necessary to prove that copying has occurred. A number of tests have been devised by courts to determine substantial similarity. They may rely on expert or lay observation or both and may subjectively judge the feel of a work or critically analyze its elements.
The Abstraction-Filtration-Comparison test (AFC) is a method of identifying substantial similarity for the purposes of applying copyright law. In particular, the AFC test is used to determine whether non-literal elements of a computer program have been copied by comparing the protectable elements of two programs. The AFC test was developed by the United States Court of Appeals for the Second Circuit in 1992 in its opinion for Computer Associates Int. Inc. v. Altai Inc. It has been widely adopted by United States courts and recognized by courts outside the United States as well.
Club Resorts Ltd v Van Breda, 2012 SCC 17, is a decision of the Supreme Court of Canada that has brought greater certainty to the question of a real and substantial connection in the assumption of civil jurisdiction by Canadian courts in matters concerning the conflict of laws.
Delrina Corporation v. Triolet Systems Inc2002 CanLII 11389, 58 OR (3d) 339, also known as Delrina II, is a 2002 Ontario Court of Appeal case which established the existence of the merger doctrine in Canadian copyright law. The plaintiff, Delrina Corp., sued Triolet Systems Inc. and Brian Duncombe for infringing its copyright of the computer program Sysview by designing similar software, called Assess. The plaintiffs were awarded an interlocutory injunction but ultimately lost at trial. Delrina Corp.’s appeal to the Ontario Court of Appeal was dismissed.
Shular v. United States, 589 U.S. ___ (2020), is an opinion of the United States Supreme Court in which the Court held that, under the Armed Career Criminal Act of 1984, the definition of “serious drug offense” requires only that the state offense involve the conduct specified in the statute. Unlike other provisions of the ACCA, it does not require that state courts develop “generic” version of a crime -- describing the elements of the offense as they are commonly understood -- and then compare the crime being charged to that "generic" version to determine whether or not they qualify under the ACCA for purposes of penalty enhancement. This decision is notable as one of many examples of Armed Career Criminal Act case law, a federal law whose provisions have resulted in significant numbers of Supreme Court cases since the law was first enacted in 1984.
