Court battle over 'base year' assessment system starts today The plaintiffs, homeowners from Pittsburgh, Franklin Park, Mt. Lebanon, Braddock and other Allegheny County municipalities, are mounting a 'full frontal challenge' of Allegheny County's 2002 base-year property assessment system, arguing the taxation method violates the Pennsylvania Constitution.Uniform is good. Onorato's plan is bad.
They want to see the county's system -- which relies on property values frozen indefinitely four years ago during the last full reassessment -- declared unconstitutional, and therefore invalid. The state constitution calls for uniform taxation of property.
