"Justices William O. Douglas and William J. Brennan, mindful that Nixon’s new appointees would join the deliberations if the cases were reargued in the fall, wanted quick action and a stronger opinion. Burger, however, wanted to go slowly. He knew the Brennan-led majority was about to announce the striking down of the death penalty on a 5-4 vote. Burger and Blackmun had dissented, as had the new Nixon appointees, Powell and Rehnquist. Burger expected the votes on abortion to line up the same way. If the abortion cases were carried over until the fall, Powell and Rehnquist would cast their votes, and the chief justice -- with Blackmun and White also on board -- could envision a new 5-4 majority that would uphold most of the state abortion laws. “This is as sensitive and difficult an issue as any in this court in my time,” Burger wrote. “Hence, I vote to reargue early in the next term.”"
