Here they come... all of those USSC decisions

Supreme Court strikes down Maine tuition aid policy that barred religious schools

The Supreme Court on Tuesday struck down a Maine education policy that made K-12 schools with religious instruction ineligible for taxpayer-backed tuition aid. The 6-3 decision broke along ideological lines, with the court’s six conservatives ruling that the state’s so-called sectarian exclusion violated constitutional religious protections.

Maine law gives school-age children the right to free public education. But because many rural districts lack a public high school, a workaround was devised that allows these students to attend nearby qualifying private schools with public assistance.

Under Maine law, however, schools that offer religious instruction had been ineligible. This exclusion prompted a challenge by Maine parents, who argued that barring families’ preferred schools from the tuition aid program based on religion violates constitutional religious rights under the First Amendment.

Pretty simple... if your sole criteria for declining aid is the idea that there is religion being taught or discussed certainly goes to the point of the first amendment, which gives freedom to people to practice their religion or talk about their religion without repercussions from the Government. 

The age old argument seems to keep coming up, with liberals demanding that the First Amendment does not provide freedom "of" religion, but freedom "from" religion... with conservatives generally disagreeing and seeing things the other way around. Look for more of these sorts of decisions that may even reverse previous decisions where Religion WAS actually used to discriminate against Government aid and other benefits.
