INDIANAPOLIS -- House Republicans voted Wednesday to start imposing $1,000 fines against Democratic legislators who have resumed their boycott of a right-to-work bill.

Democrats refused to enter the chamber Wednesday to allow a quorum, instead holding an open caucus inside the Statehouse rotunda, surrounded by hundreds of union supporters.

"They have tried to stop you from being in this building. You wouldn't allow it to happen," Democratic House Minority Leader Patrick Bauer told the cheering crowd.

Bauer and Republican Speaker Brian Bosma squabbled Tuesday over what Bauer called Bosma's "manipulation" of an effort to put right-to-work legislation on the ballot.

The two leaders fought over who broke a truce negotiated designed to keep Democrats in the House chamber long enough for a vote on the Republican plan to ban union contracts with mandatory representation fees.

The legislation has brought hundreds of labor protesters to the Statehouse almost daily and spurred Democrats to frequently block action by denying Republicans the number of lawmakers needed to conduct any business.

Lawmakers had planned Tuesday to vote on whether to put the right-to-work bill to referendum before voters this fall. But Bauer said he found out late Monday that state lawyers had raised questions about the constitutionality of such a measure. He called it a trick from Bosma designed to give Republicans cover to vote against the referendum proposal.

"We will not let the Republicans press a crown of thorns upon the brows of the working families of Indiana," said Rep. Terry Goodin, D-Austin.

Among Wednesday's crowd were Teamsters members were wearing shirts with an XLVI and a slash, a clear reference to the Super Bowl, many shouting "Occupy the Super Bowl."

Teamsters Local 135 Director Jeff Combs said the union is discussing plans to protest right-to-work at the game so they can bring their cause to a national audience.

"We'll roll 100 trucks in here, 200 if we need to and put in thousands of people if we have to" to surround the stadium, Combs said.

A representative with the Super Bowl Host Committee told RTV6 that public safety officials will be ready to deal with any disruptions.

"The people in Indianapolis, the heart that's gone into this, the soul that's gone into it, will shine throughout our community, and with the international spotlight, we're excited to show the world what we've done in preparation for this," said Dianna Boyce with the Super Bowl Host Committee.

Bosma adjourned the House just before noon Wednesday.
