Comprehensive vocabulary flashcards covering Scots law concepts, public and private law, elements of criminal liability, mens rea, actus reus, and common law classifications of crime.

Law

One of the rules in a system of law that deals with a particular type of agreement, relationship, or crime, under which a person or group is held accountable and sanctions can be enforced if it is broken.

Scots Law

The distinct legal system of Scotland, which features its own laws and courts, and is divided into two primary categories: public law and private law.

Public Law

The branch of law that regulates the relationship between the individual and the state, governs state powers to make, enforce, amend, and repeal laws, and addresses acts that affect society as a whole.

Private Law

The category of law dealing with issues and legal relationships between two or more individuals or private organizations, such as divorce contracts or property boundary disputes.

Administrative Law

A form of public law that involves rules surrounding public bodies, such as the NHS, local councils, and licensing laws.

Criminal Law

A branch of public law comprising rules that forbid conduct considered sufficiently harmful to society as a whole to merit the label criminal, legally constituting an act against the state.

Crown Office and Procurator Fiscal Service

The public prosecution service in Scotland responsible for prosecuting criminal cases on behalf of the state.

Actus non facit reum nisi mens sit rea

A foundational legal maxim meaning "the act cannot be guilty unless the mind is also guilty."

Mens Rea

The Latin term for "guilty mind," representing the mental element of an offence required to establish criminal intent and differentiate intentional conduct from accidental actions.

Intention (Mens Rea)

A state of mind where the accused planned, meant, deliberately, or wilfully set out to commit an offence, determined through a subjective test of what the defendant was actually thinking.

Recklessness (Mens Rea)

A form of mens rea defined as "a total indifference to and disregard for the safety of the public," or pursuing a course of action without considering the risks.

Negligence (Mens Rea)

A form of criminal fault characterized by careless behaviour and failing to adhere to a duty of care where one legally exists, lacking the direct desire to cause a specific consequence.

Knowledge (Mens Rea)

A state of mind where a person is fully aware that their actions will bring about certain predictable results (such as handling goods known to be stolen) but proceeds regardless.

Strict Liability Offence

An offence where the prosecution is not required to prove mens rea (guilty mind), such as being drunk and in charge of a mechanically propelled vehicle on a public road or speeding.

Actus Reus

The Latin term for "guilty act," referring to the voluntary conduct, physical act, or legally culpable state that an individual carries out of their own free will.

Three Elements of Criminal Liability

The three criteria required to find a defendant liable for an offence: guilty conduct (actus reus), a guilty state of mind (mens rea), and the absence of a valid defence (such as self-defence, coercion, or necessity).

Overt or Positive Act

A classification of actus reus consisting of physical movement or active behaviour that is intrinsically criminal or likely to cause bodily harm or property damage.

Breach of the Peace

An offence defined as any behaviour serious enough to cause ordinary people alarm and threaten serious disturbance to the community, assessed via an objective test for reasonable fear.

Omission (Actus Reus)

A failure to act or perform a legal obligation, often associated with a statutory requirement (such as Road Traffic Acts) or a recognized duty of care.

R v Pittwood (1902)

A legal case illustrating criminal liability arising from an omission where a contractual duty of care existed, involving a level crossing gatekeeper who failed to close the gate.

State of Affairs (Actus Reus)

A classification of actus reus characterized by "being" rather than active "doing," involving the circumstances, status, or condition of a person (such as unlawful possession of a weapon or being in charge of a vehicle while intoxicated).

Crimes Against the State

Common law offences affecting the security or integrity of the state as a whole, including treason, perjury, perverting the course of justice, and defrauding government bodies such as HMRC or the Department for Work and Pensions.

Crimes of Dishonesty and Against Property

Common law offences involving the taking or appropriation of property without the owner's consent, knowing that the accused has no right to it (e.g., theft, fraud, money laundering, and bribery).

Crimes Against the Person

A broad category of criminal offences committed against the will of an individual that usually involve bodily harm or the threat of bodily harm, including assault, battery, and domestic violence.
