He also said the younger generation of lawyers has supported him in "democratising the institution", but acknowledged constitutional lawyers and jurists attacked him from every side.
"What is the law or the scripture which says judges cannot hold press conferences? They shouldn't hold a press conference to defend their judgments, I knew that when I opened my mouth I would have to go through all this and I was willing to take it...," he added.
Justice Chelameswar had turned down the Supreme Court Bar Association (SCBA)'s request to participate in a farewell function it wanted to arrange for him, saying he wanted his retirement to be a "private affair". However, later in the evening on Friday, he attended a reception organised by Lawyers Collective.
On his last working day on Friday, he shared a bench with Chief Justice Dipak Misra, a custom and practice of the Supreme Court.
The 65-year-old judge has been at loggerheads with Justice Misra over the functioning of the top court including the allocation of sensitive cases and on recommendation of judges for appointment to higher judiciary.
At the gathering of Lawyers Collective, an advocacy NGO founded by activist senior lawyers Indira Jaising and Anand Grover, on Friday, Justice Chelameswar said in the last six months, wherever he went in the country, people have come up to him and said: "We are glad you did it".
He said he was willing to face the consequences of his actions, whether it be his abstention from collegium meetings after the NJAC judgment or the press conference he held.
He told the younger generation present at the gathering that they required to have courage and determination to fight the system if they want to bring a good change.
"But if you are convinced on principle that the fight is to be carried on for good change, please go ahead. If you have an opinion, speak up," he added.
