May 30 (Bloomberg) -- The Supreme Court has yet to decide
this year’s attention-grabbing cases on same-sex marriage,
affirmative action and the Voting Rights Act. But last week, a
divided court decided Arlington v. FCC, an important victory for
Barack Obama’s administration that will long define the
relationship between federal agencies and federal courts.
The underlying question was this: If a law is ambiguous,
who gets to interpret it? Federal judges or the agency that
carries it out? Who interprets the crucial ambiguities in the
Affordable Care Act, the Clean Air Act or the Wall Street Reform
and Consumer Protection Act?
