The Supreme Court said Tuesday that it would consider a legal challenge to President Obama’s overhaul of the nation’s immigration rules, agreeing to examine the reach of presidential power as it decides the fate of one of his most far-reaching executive actions.
The court, which has twice rejected challenges to Mr. Obama’s signature legislative victory by upholding his health care law, will now rule on the president’s plan to protect millions of illegal immigrants from deportation and allow them to work indefinitely in the country legally.
The justices raised the possibility of a broad decision by taking the unusual step of adding their own question to the case, asking the parties to address whether Mr. Obama had violated his constitutional obligations to enforce the nation’s laws. The answer to that question could significantly alter the scope of presidential power in realms far beyond immigration.
“The court’s decision could redefine the balance of power between Congress and the president,” said Stephen Yale-Loehr, a law professor at Cornell.
