A Judgement is not final till it is signed and sealed. It is important for a judge to be open till it is sealed.
This post explains the same with an incident, at an early stage of my career, from the court of Satish Chandra J. (01-09.1924 – 24.01.2000). He was a judge of the Allahabad High Court, when I joined the Bar and retired as the Chief Justice of the Calcutta High Court on 31st August 1986.
