Last October, the American Law Institute, the group that established standards for the death penalty in America, voted to withdraw its support of the practice it helped to define. This decision, according to New York Times columnist Adam Liptak, “represents a tectonic shift in legal theory.” In his most recent column, he descirbes it as the single most significant development surrounding the death penalty in the past year.

Liptak writes:

The institute’s recent decision to abandon the field was a compromise. Some members had asked the institute to take a stand against the death penalty as such. That effort failed.

Instead, the institute voted in October to disavow the structure it had created “in light of the current intractable institutional and structural obstacles to ensuring a minimally adequate system for administering capital punishment.”

That last sentence contains some pretty dense lawyer talk, but it can be untangled. What the institute was saying is that the capital justice system in the United States is irretrievably broken.

A study commissioned by the institute said that decades of experience have proved that the system cannot reconcile the twin goals of individualized decisions about who should be executed and systemic fairness. It added that capital punishment is plagued by racial disparities; is enormously expensive even as many defense lawyers are underpaid and some are incompetent; risks executing innocent people; and is undermined by the politics that come with judicial elections.

Roger S. Clark, who teaches at Rutgers School of Law in Camden, N.J., and was one of the leaders of the movement to have the institute condemn the death penalty outright, said he was satisfied with the compromise. “Capital punishment is going to be around for a while,” Professor Clark said. “What this does is pull the plug on the whole intellectual underpinnings for it.”

The decision does not mean an immediate end to the death penalty, but it may indicate some interesting legal and ethical developments are in store for 2010.
