Six years ago, I met with Erica Smith of the Institute for Justice in a Montana coffee shop, where I agreed to be the lead plaintiff in a lawsuit about the use of funds from a state education tax credit program for children attending religious schools. This past June, in Espinoza v. Montana Department of Revenue, the U.S. Supreme Court reversed Montana’s highest court and ruled that if parents use funds from the program to access private education, religious school options cannot be excluded.
