The CDC estimates that more than half of all college students are having sex. This probably puts accessible and affordable birth control pretty high on sexual active priority lists. The Obama administration’s contraception mandate is a boon to most college students who had trouble affording birth control, and some universities are embracing the policy full heartedly.

But not every university.

Three new lawsuits have been filed on behalf of colleges challenging the policy mandating that employees of religious institutions like schools, colleges, and hospitals have access to contraceptive services free of charge.

The Alliance Defense Fund filed suits on behalf of Pennsylvania school Geneva College, which is affiliated with the Reformed Presbyterian Church, and Louisiana College, a Southern Baptist institution in Louisiana.

The Becket Fund for Religious Liberty also filed a suit on behalf of Ave Maria University, a conservative Catholic institution in Florida.

All three lawsuits follow the president’s announcement on Feb. 10 that religious employers would not have to pay for this coverage, a policy change that sought to accommodate the objections of some religious groups.

With the new lawsuits, at least half-dozen organizations are challenging the mandate.

Catholic institutions, backing the Church’s historical stance against artificial contraception, have led the fight, with lawsuits filed by Belmont Abbey College, Priests for Life and EWTN Global Catholic Television Network.

But evangelicals have joined the fight as well, since such “morning-after pills” like Plan B and Ella are among the list of contraceptives that insurers must provide. Pro-lifers consider these to be potential “abortifacients.”

The President has said he struck the right balance of protecting religious liberty while ensuring access to free contraception. He also has touted excusing more employers from the mandate and giving nonexempt employers an extra year before they must comply.
