(FOX NEWS) — WASHINGTON – Arguing that President Obama’s health care law was designed to fix an intractable national problem of exploding costs during a crisis, the administration submitted its opening brief to the Supreme Court Friday defending the law as both necessary and constitutional.

The 63-page brief is the first salvo in one of four cases accepted by the high court challenging the controversial health care law. Those cases will be heard in March. This filing is specifically focused on the suit challenging the law’s so-called individual mandate, or requirement to buy health insurance.
