By 1864, the First Circuit Court on Oahu was gradually phased out of existence and its judicial powers were transferred to the Supreme Court.
In 1865 the circuit court was abolished, but the appellate jurisdictions in chambers remained as a function. Such proceedings were referred to as Intermediary Court, but the person presiding was called the First Circuit Court Judge. Appellate jurisdictions in chambers remained as a circuit court function and such proceedings were referred to as Intermediary Court. In 1874, the intermediary function of the First Circuit Court judge was transferred to the Supreme Court, which now held both original and appellate jurisdiction for the island of Oahu. The term Intermediary Court continued to be used when a Supreme Court Justice presided in that role.
In 1892, the functions of the Supreme Court were restricted to those of an appellate court. Its functions as a circuit court were assumed by a reestablished First Circuit Court.
