The Philadelphia Board of Ethics approved amendments to the city’s campaign finance rules this week. Included in the amendments is a more expansive definition of third party support of a candidate.

Campaign materials produced by a candidate and subsequently used by an individual or PAC, independent of the candidate, now constitutes an in-kind contribution subject to the city’s contribution limits. The new rule is intended to curb a growing trend among candidates of posting videos on the internet, allowing third parties to take the material and independently create political advertisements.

The board unanimously approved the changes in an expedited manner to ensure the new rules would cover the impending 2015 mayoral race.
