CNN  — 

Supreme Court Justice Stephen Breyer’s plans to retire from the high court after nearly three decades on the bench are set to pave the way for a speedy confirmation process for his eventual successor.

Breyer, the court’s senior liberal justice, had been facing intense retirement calls from some Democrats who feared that if he didn’t step down while the party controlled the White House and held a razor-thin majority in the Senate, Republicans could have eventually been the party to determine the fate of his replacement.

Breyer is expected to stay on until the end of the court term and until a replacement is confirmed, a well-placed source familiar with the matter told CNN.

Already, Breyer’s retirement plans have prompted Senate Democrats to begin eyeing a quick confirmation process for whomever President Joe Biden nominates to replace him, with Senate Majority Leader Chuck Schumer saying on Wednesday that he will follow a similar timeline to the one that Republicans employed to confirm Amy Coney Barrett to the court in 2020, according to a source familiar with this thinking.

Senate Democrats only need a simple majority of 51 votes to confirm a new justice once one is formally nominated. Currently, there are just 48 Democrats in the Senate, with two independents who caucus with the party. Should no Republicans join Democrats in voting in favor of Biden’s nominee, Vice President Kamala Harris would need to cast a tie-breaking vote in order to get the nominee over the finish line.

Here’s a look at how long it has taken to confirm past Supreme Court justices:
