'“It’s neither minimalist nor restrained to overrule cases while pretending you are not,” Walter E. Dellinger III, who served as acting solicitor general in the Clinton administration, said in an online conversation on Slate. Mr. Dellinger’s point was that “there can also be a significant cost to the coherence of the system” if lower courts are in the dark as to which precedents they must still rely on.
Chief Justice Roberts, operating on a long timeline at 52, may be responding to a different imperative. Openly overturning numerous precedents early in his tenure would invite criticism that the Roberts court has an agenda to “radically shift American law,” said Thomas C. Goldstein, a student of the court who argues there often.
The conservative alliance at the court may be fractious but not fragile, strong enough to withstand Justice Scalia’s “tweaking and needling,” as Prof. Richard W. Garnett of Notre Dame Law School describes it.
“I look at it as a bit of a kabuki dance,” said Professor Garnett, who clerked for Chief Justice Rehnquist and is close to the court’s conservatives. He said he had no doubt that Justice Scalia had “huge respect for the new chief as a person and as a lawyer.”
What is visible now, he said, is the latest iteration of the endless struggle between the need for stability in the law and the desire to correct previous mistakes.
“Different people who call themselves conservatives resolve that tension in different ways,” Professor Garnett said, adding that Justice Scalia was “laying down markers, making sure the arguments are out there to be used in later cases.”'
