Article 164(3) confers the Court of Appeal jurisdiction to hear appeals from the High Court or any other court or tribunal as prescribed by an Act of Parliament.

The exercise of jurisdiction by the Court of Appeal is underpinned by the principles enshrined in Article 159 of the Constitution which provides that:

1. 1. Judicial authority is derived from the people and vests in, and shall be exercised by, the courts and tribunals established by or under this Constitution.
   2. In exercising judicial authority, the courts and tribunals shall be guided by the following principles—
      1. a) justice shall be done to all, irrespective of status;
      2. b) justice shall not be delayed;
      3. c) alternative forms of dispute resolution including reconciliation, mediation, arbitration and traditional dispute resolution mechanisms shall be promoted, subject to article 159 clause (3);
      4. d) justice shall be administered without undue regard to procedural technicalities; and
      5. e) the purpose and principles of this Constitution shall be protected and promoted.

The practice and procedure of the Court is regulated by the Appellate Jurisdiction Act Cap 9 while its administrative procedures are guided by the Court of Appeal (Organisation and Administration) Act 2015 (Link to the Act)
