The Connecticut Appellate Court is the court of first appeals for all cases arising from the Connecticut Superior Courts. Its creation in 1983 required Connecticut's voters and legislature to amend the state's constitution. The court heard its first cases on October 4, 1983.^[1] The Appellate Court was also a partial successor to the former Appellate Session of the Superior Court, a court established to hear appeals in minor matters (e.g., misdemeanors and minor civil matters.)^[2][3]

The Connecticut Appellate Court is composed of nine Appellate Court Judges. However, retired Judges of the Appellate Court and of the Supreme Court can still sit on Appellate Court panels, as needed. Retired Chief Justices Ellen Ash Peters, Francis McDonald, and William Sullivan continue to sit regularly with the Appellate Court, as do retired Justices David Borden and Barry Schaller, retired Appellate Court Chief Judges Antoinette Dupont and William Lavery, and a battery of other retired Appellate Court Judges (including Socrates Mihalakos, Joseph Pellegrino, George Stoughton, and Thomas West, among others). If the Chief Court Administrator is a Judge of the Appellate Court, the Appellate Court is authorized to have 10 seats. (Judge Joseph Pellegrino fulfilled this role and during his time, the Court had 10 members.)^[4] Some Judges of the former Appellate Session of the Superior Court went on to serve on the Appellate Court, notably, John Daly and Francis X. Hennessy.
