The Senate Judiciary Committee held a rare “do-over” vote Friday to clarify its desire to strip immunity for telecommunications firms from a proposed overhaul of the nation’s electronic surveillance law.

The move puts the Judiciary Committee at odds not only with the Bush administration but also with the Senate Intelligence Committee, which approved a version of the bill that includes retroactive legal immunity for telecommunications carriers that cooperated with the Bush administration’s warrantless surveillance program earlier this decade. The full Senate will now have to decide the issue when it takes up the measure.

Senate Majority Leader Harry Reid , D-Nev., was noncommittal when asked which version of the bill he would support. President Bush is expected to veto any surveillance measure that does not include retroactive immunity.

The Judiciary Committee ostensibly voted to send its version to the Senate on a 10-9 party-line vote Thursday, with several committee members voting by proxy. But committee rules dictate that a majority of members actually present must vote in favor for a question to carry. It was unclear Thursday night whether a majority of senators actually in the room had done so.

To avoid potential challenges going forward, Chairman Patrick J. Leahy , D-Vt., scheduled a quick meeting off the Senate floor Friday morning to take a second vote. The committee ratified its decision by voice vote.
