The Supreme Court will hear arguments on President Obama's healthcare law over a three-day span in late March.
The schedule further confirms the universal expectation that the court will issue a ruling on the healthcare law next June, at the height of the 2012 campaign.
On March 27, the justices will hear two hours of arguments on the core question of whether the mandate is unconstitutional.
And on March 28, the court will hear arguments on two issues: how much, if any, of the law's other provisions can be upheld if the mandate is unconstitutional, and whether the health law's Medicaid expansion is constitutional.
The court will not hear any other cases during that three-day span.
