Gov. Jan Brewer faces a May 9 deadline for filing her appeal of a ruling that prevents police from enforcing yet another portion of Arizona's 2010 immigration enforcement law.

Brewer is appealing U.S. District Judge Susan Bolton's Feb. 29 ruling that stopped police from enforcing the law's prohibition on blocking traffic when people seek or offer day labor services on streets.

The ban was among a handful of provisions that Bolton allowed to take effect in her July 2010 decision that halted enforcement of the law's most controversial elements.

The governor had previously told the courts she would appeal the February ruling.

The U.S. Supreme Court heard arguments last week in Brewer's appeal of Bolton's July 2010 ruling on other elements of SB 1070.
