A Denver lawmaker on Friday attempted to punish a University of Colorado professor for supporting Gov. Bill Ritter's primary job-creation proposal.

House Bill 1001 by Rep. Joe Rice, D-Littleton, allows companies that create 20 or more jobs to get a 50 percent tax credit for each job.

Democratic Rep. Joel Judd is not a fan of the bill.

Several weeks ago, Professor Richard Wobbekind, of CU's Leeds School of Business, told lawmakers the bill would have positive impacts for the state. So Judd proposed an amendment Friday that the Leeds school fund the entire tax credit program.

Several lawmakers said it was inappropriate.

"We need to be very careful not to do special-interest legislation to penalize one group," said Rep. Jim Riesberg, D-Greeley.

The House Appropriations Committee approved the job- creation proposal, but the amendment lost by a 9-3 vote.

Amendment supporters were Judd, Republican Rep. Don Marostica, of Loveland, and Democratic Rep. Jack Pommer, of Boulder.

In other action:

* The Senate Appropriations Committee backed a bill raising marriage and divorce fees to pay for programs to help domestic abuse victims. The measure would raise the marriage license fee from $10 to $30. Divorce petitions would go from $220 to $230, and divorce responses would be raised by $10 to $116.

* Cities would be able to use photo radar to catch speeders in more places under a bill given initial backing by the Senate. Currently, cities can use photo radar only near parks, schools, construction zones and streets with speed limits under 35 mph. SB 143 would allow it on streets with speed limits up to 55 mph. Fines would be capped at $40.

* The Senate gave initial backing to SB 29, requiring school buses to be equipped with seat belts over the next five years.

* The Senate voted 29-5 to give final backing to a bill requiring carbon monoxide detectors in homes.
