Judicial deference describes the courts' practice of accepting the decisions of the legislature and executive as authoritative. Such practice may be justified on the grounds of legitimacy-based deference or expertise-based deference. In the former, judicial deference is justified on the ground that the decision-maker has superior democratic credentials compared to the courts. Under the Westminster system of constitutional government, the judiciary is hesitant to intrude into the powers of the legislature and the executive. In the latter, judicial deference is justified on the ground that the judiciary may not have the requisite information and expertise to decide on a matter competently.

Judicial deference has also been described as a range of judicial techniques which the courts use to increase the discretion allowed to the legislature and executive. In administrative law, courts generally decide on the legality and not the merits of a decision taken by a public body. In constitutional law, courts have exercised judicial deference in certain ways, such as applying a presumption of constituitionality and taking a purposive approach in interpreting the Constitution.
