The campaign for Proposition 8, California's 2008 voter-approved ban on same-sex marriage, is facing a $49,000 fine for allegedly violating campaign disclosure laws during the 2008 election.

California's Fair Political Practices Commission proposed the fine after an investigation revealed that - Yes on 8 failed to properly report over $1 million in campaign contributions.

The Sacramento Bee reported:

[Yes on 8] failed to report $1,169,292 in contributions under the timelines required by state law, including $508,150 in late contributions of $1000 or more given in the final days of the campaign. It also found that the committee failed to identify the donor behind a $10,000 wire transfer. - Yes on 8 faces 18 counts of violating state political laws. The group has agreed to both the violations and the fines, but the commission will meet to determine an appropriate recommendation on August 16.
