The appeals court normally takes more than a year to rule a case, though it likely will be lobbied to make this case a priority. In the Meantime, the Legislature also is mulling the possibility of rewriting the measure to make it legal and then sending it back to the voters for a revote--giving its detractors another chance to defeat it.

Measure 7 requires compensation to property owners for government action that restricts the use of their land and lowers their property value. As foretold in his decision to issue a preliminary injunction against its implementation in December, Lipscomb ruled that the measure violates two requirements for constitutional amendments.
