The Senate has blocked the interim appointment of one of George W. Bush's torture enablers by using pro forma sessions, a parliamentary technique by which the upper chamber does not formally adjourn. With the Senate technically still in session, Bush cannot make appointments without their approval. Does this mean Majority Leader Harry Reid has finally grown a pair? It's doubtful.

A nine-second session gaveled in and out by Sen. Jim Webb, D-Va., prevented Bush from appointing as an assistant attorney general a nominee roundly rejected by majority Democrats. Without the pro forma session, the Senate would be technically adjourned, allowing the president to install officials without Senate confirmation.

The business of blocking Bush's recess appointments was serious. It represents an institutional standoff between Congress and the president that could repeat itself during Congress' vacations for the remainder of Bush's presidency.

In such situations, pro forma sessions also could give Bush some political cover on popular legislation he doesn't want to sign. When Congress is holding pro forma sessions and is not formally adjourned, a bill sent to a president automatically becomes law 10 days after he receives it — excluding Sundays — unless he vetoes it.

That could be the fate of two bills Congress passed last week. One growing out of the Virginia Tech massacre makes it harder for people with mental illness records to buy guns. The other makes it easier for journalists and others to obtain government documents through the Freedom of Information Act. The FOIA bill, for example, would become law on New Year's Eve if not vetoed before then, according to Senate Judiciary Committee officials.
