Article 223 of CoI : Article 223: Appointment of acting Chief Justice.

Explanation using Example

Example 1:

The Chief Justice of the High Court of Delhi is scheduled to retire on June 30th. However, the process of appointing a new Chief Justice is still ongoing and will not be completed by the time of the retirement. To ensure that the High Court continues to function smoothly, the President of India appoints Justice A, one of the senior judges of the Delhi High Court, to act as the Chief Justice until a new Chief Justice is officially appointed.

Example 2:

The Chief Justice of the High Court of Karnataka is on a medical leave for three months due to a serious health condition. During this period, the President of India appoints Justice B, another senior judge of the Karnataka High Court, to perform the duties of the Chief Justice. This ensures that the administrative and judicial functions of the High Court are not disrupted during the Chief Justice's absence.
