Now it's everyone's problem. The legal battle over Allegheny County's base-year property assessment system likely will spread to the rest of the state now that Common Pleas Court Judge R. Stanton Wettick has declared it violates the state constitution. Wettick also ordered the county to conduct a reassessment for use in 2009, or, at the latest, 2010 if the case is still under appeal. County Chief Executive Dan Onorato, striking a defiant tone, said the judge doesn't have the authority to dictate a reassessment timeline. Allegheny County won't go through another reassessment unless every other county has to, Onorato said.
