A Senate bill would repeal a 2007 law that changed how property taxes from crude oil refinery expansion would be split among school districts.

The 2007 law originally was designed to define property tax exemptions for trailers.

According to legislative records, it was changed during final negotiations to say property taxes from proposed liquefied natural gas terminals and improvements or expansions at crude oil refineries would be shared by all school districts in a county, not solely by the district where the industry was located.

The bill to repeal the law was approved Tuesday by the Senate Finance Committee.

The city of Pascagoula filed a lawsuit last October challenging the constitutionality of the law.

The bill is Senate Bill 2797.
