Multnomah County Circuit Judge Eric Bloch struck down voter-approved limits on campaign donations to candidates running for county offices.

Judge Bloch’s ruling stated the $500 limit on donations violates Oregon’s expansive free expression guarantees in the Oregon Constitution.

The decision mirrors one the judge issued in March 2018 striking down limits for Multnomah County races, citing a 1997 Oregon Supreme Court decision.

Judge Bloch upheld portions of the voter-approved campaign rules that require Portland political advertisements to prominently disclose their top five financial backers.

Supporters of the law say they will appeal the decision.

In Oregon, a Multnomah County Circuit Court judge found county campaign finance reforms unconstitutional.

Judge Eric Bloch ruled the voter-approved limitations on campaign contributions and independent expenditures were impermissible under the free speech guarantees within the Oregon Constitution, citing a related Oregon Supreme Court opinion.

He ruled they also cannot force disclosure of the largest contributors to political mailers and other forms of communication.

The Multnomah County voters adopted the reforms with an 89 percent “yes” vote in November 2016. An appeal of the judge’s decision is expected.
