A coalition of at least 120 wealthy Texas school districts has filed a lawsuit challenging the state's school finance system.
The lawsuit alleges that the state's system of paying for public education is inadequate and unconstitutional.
The Texas School Coalition is made up of more than 120 Texas school districts that give money back to the state under the so-called Robin Hood school funding plan.
Six districts are named as plaintiffs in the lawsuit.
The schools argued Friday that because so many districts are taxing at the maximum allowable rate, the school property tax has effectively become a statewide property tax, which is unconstitutional in Texas.
They're also arguing that the Legislature hasn't been putting enough money into the system to meet the constitutional mandate for an "adequate" education.
