"The Justices' order does require the Little Sisters to tell the government, in writing, that they are non-profit groups 'that hold themselves out as religious and have religious objections to providing coverage for contraceptive services.' That was a procedural wrinkle that the Court itself invented, outside the rules laid down by the government. If the Little Sisters do make that substitute kind of notification, then the government, under the order, is barred from enforcing the mandate against them. At no point in the case as it moves forward, the order stressed, are the Little Sisters required to file Form 700 with the government, or to send copies of it to the separate entity that operates their employee health benefit plan."
