The San Diego campaign finance case, Thalheimer v. City of San Diego, will be heard by the Ninth Circuit in Pasadena on October 4. I plan to argue on behalf of the City of San Diego.
One of the questions posed in the case is the constitutionality of San Diego law barring corporations, unions, and other non-human entities from contributing directly to candidates for City office. Also at issue is whether political parties have a constitutional right to contribute directly to candidates in nonpartisan elections.
