The move spells far-reaching implications for jurists and politicians in the chaotic South Asian democracy where the Supreme Court often sets the agenda on matters of policy and orders measures taken in the public interest.
Exposing a rift with Chief Justice Dipak Misra, some of the Supreme Court's most senior judges told a news conference the issues involving its administration were serious enough to prompt them to go public.
"The four of us are convinced that unless this institution is preserved and it maintains its equanimity, democracy will not survive in this country," Justice Jasti Chelameswar said on the lawns of his residence in the Indian capital.
The justices gave few details of the incidents they were referring to, but released a letter they had written to Misra.
In the letter, they mentioned instances of cases with "far-reaching consequences for the nation and the institution" that were selectively assigned to judges by the chief justice without any rational "basis for such assignment".
All Supreme Court judges should be involved in setting the procedures used to hire and promote judges in various courts in the country, including the high courts, they added.
The chief justice did not immediately respond to telephone calls from Reuters to seek comment.
Law Minister Ravi Shankar Prasad declined to comment.
Two close aides of Prime Minister Narendra Modi said he was looking into the matter and had summoned top law ministry officials for consultations.

The trial involved Amit Shah, the president of the ruling Bharatiya Janata Party, and several police officials from Modi's western home state of Gujarat.
The BJP declined to comment.
Separately, last November, the chief justice overturned an order by Chelameswar that referred a case to a bench of the five senior-most judges. At the time, Misra said he was the "master of the roster".
Some Supreme Court lawyers praised the justices' action.
"Looking at its own flaws is the first step to correcting an institution, to deepening true constitutional democracy," said Karuna Nundy, a Supreme Court lawyer.
But there was also criticism over the public nature of the rift. The public spat was distressing, a former attorney-general of India, Soli Sorabjee, told the India Today news channel.
"The public shouldn't see that the judiciary is a divided house," he said.
The Supreme Court has 25 judges appointed by India's president, including the chief justice, and each retires at the age of 65, the court says on its website.
The four justices at Friday's news conference - besides Chelameswar, they included Ranjan Gogoi, Madan Lokur and Kurian Joseph - are the most senior after Misra.
Three of them are scheduled to retire this year, while Gogoi is in line to be the next chief justice, based on seniority.
Efforts to alert the chief justice that certain things were not in order and that remedial measures were needed had failed, prompting the news conference, Chelameswar said.
Asked if the chief justice should be impeached, Chelameswar said, "That's for the nation to decide."
"I think this is the first of many things to come," said Alok Kumar Prasanna, a lawyer and legal researcher. "It seems clear to me that there's a war going on."
