The Post’s E.J. Dionne Jr. discusses Citizens United in his column this morning.

If you wonder what judicial activism looks like, consider one of the court’s final moves in its spring term.

The justices had before them a simple case, involving a group called Citizens United, that could have been disposed of on narrow grounds. The organization had asked to be exempt from the restrictions embodied in the 2002 McCain-Feingold campaign-finance law for a movie critical of Hillary Clinton that it produced during last year’s presidential campaign. Citizens United says it should not have to disclose who paid for the film.

Rather than decide the case before it, the court engaged in a remarkable exercise of judicial overreach. It postponed its decision, called for new briefs and scheduled a hearing this September on the broader question of whether corporations should be allowed to spend money to elect or defeat particular candidates.
