Fundamental justice in the context of "Legal procedure"

Procedural law, adjective law, in some jurisdictions referred to as remedial law, or rules of court, comprises the rules by which a court hears and determines what happens in civil, lawsuit, criminal or administrative proceedings. The rules are designed to ensure a fair and consistent application of due process (in the U.S.) or fundamental justice (in other common law countries) to all cases that come before a court.

Substantive law, which refers to the actual claim and defense whose validity is tested through the procedures of procedural law, is different from procedural law. In the context of procedural law, procedural rights may also refer not exhaustively to rights to information, access to justice, and right to counsel, rights to public participation, and right to confront accusers, as well as the basic presumption of innocence (meaning the prosecution regularly must meet the burden of proof, although different jurisdictions have various exceptions), with those rights encompassing general civil and political rights. In environmental law, these procedural rights have been reflected within the UNECE Convention on "Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters" known as the Aarhus Convention (1998).

Procedural justice is the idea of fairness in the processes that resolve disputes and allocate resources. One aspect of procedural justice is related to discussions of the administration of justice and legal proceedings. This sense of procedural justice is connected to due process (U.S.), fundamental justice (Canada), procedural fairness (Australia), and natural justice (other Common law jurisdictions), but the idea of procedural justice can also be applied to nonlegal contexts in which some process is employed to resolve conflict or divide benefits or burdens. Aspects of procedural justice are an area of study in social psychology, sociology, and organizational psychology.

Procedural justice concerns the fairness (formal equal opportunity) and the transparency of the processes by which decisions are made, and may be contrasted with distributive justice (fairness in the distribution of rights and outcomes), and retributive justice (fairness in the punishment of wrongs). Hearing all parties before a decision is made is one step which would be considered appropriate to be taken in order that a process may then be characterised as procedurally fair. Some theories of procedural justice hold that fair procedure leads to equitable outcomes, even if the requirements of distributive or restorative justice are not met. It has been suggested that this is the outcome of the higher quality interpersonal interactions often found in the procedural justice process, which has shown to be stronger in affecting the perception of fairness during conflict resolution.

Audi alteram partem (or audiatur et altera pars) is a Latin phrase meaning "listen to the other side", or "let the other side be heard as well". It is the principle that no person should be judged without a fair hearing in which each party is given the opportunity to respond to the evidence against them.

"Audi alteram partem" is considered to be a principle of fundamental justice or equity or the principle of natural justice in most legal systems. This principle includes the rights of a party or its lawyers to confront the witnesses against them, to have a fair opportunity to challenge the evidence presented by the other party, to summon one's own witnesses and to present evidence, and to have counsel, if necessary at public expense, in order to make one's case properly.

Section 7 of the Canadian Charter of Rights and Freedoms is a constitutional provision that protects an individual's autonomy and personal legal rights from actions of the government in Canada. There are three types of protection within the section: the right to life, liberty and security of the person. Denials of these rights are constitutional only if the denials do not breach what is referred to as fundamental justice.

This Charter provision provides both substantive and procedural rights. It has broad application beyond merely protecting due process in administrative proceedings and in the adjudicative context, and has in certain circumstances touched upon major national policy issues such as entitlement to social assistance and public health care. As such, it has proven to be a controversial provision in the Charter.
