So you wanted to "play nice" with the White House on those Supreme Court nominees a couple years ago, did you? Formed that "Gang of 14" to keep our collective wheels spinning in greased grooves, no nasty contentious filibusters--right?

The result:

Precedents Begin to Fall for Roberts Court

No Supreme Court nominee could be confirmed these days without paying homage to the judicial doctrine of "stare decisis," Latin for "to stand by things decided." Yet experienced listeners have learned to take these professions of devotion to precedent "cum grano salis," Latin for "with a grain of salt."

Both Chief Justice John G. Roberts Jr. and Justice Samuel A. Alito Jr. assured their Senate questioners at their confirmation hearings that they, too, respected precedent. So why were they on the majority side of a 5-to-4 decision last week declaring that a 45-year-old doctrine excusing people whose "unique circumstances" prevented them from meeting court filing deadlines was now "illegitimate"?

It was the second time the Roberts court had overturned a precedent, and the first in a decision with a divided vote. It surely will not be the last...

Sometimes the court overrules cases without actually saying so. Some argue that this is what happened in April, when a 5-to-4 majority upheld the federal Partial-Birth Abortion Ban Act without making much effort to reconcile that ruling with a decision in 2000 that found a nearly identical Nebraska law unconstitutional.

As a technical matter, the new decision, Gonzales v. Carhart, left the earlier ruling still on the books, doing its overruling "by stealth, without having the grace to admit that is what they were doing," in the words of Ronald Dworkin, the legal philosopher, who wrote a highly critical appraisal of the new decision in The New York Review of Books last month. "Justices Roberts and Alito had both declared their intention to respect precedent in their confirmation hearings, and no doubt they were reluctant to admit so soon how little those declarations were worth," Professor Dworkin said from London in an e-mail message.
