Florida: So-called ‘anti-Shariah’ bill passes House
Posted on April 19, 2013 by creeping

The media can’t even hide their disdain, much like Obama when he loses. Just check out the title. via TALLAHASSEE: Abortion, ‘anti-Shariah’ bills pass House, but fate uncertain in Senate – Florida – MiamiHerald.com.

House lawmakers also approved a measure that requires that Florida law trump foreign law in family law court. The bill, HB 351, would apply to all foreign laws, though critics say it is targeting Islamic law, called Shariah.

Supporters have yet to cite a case where the change in law is needed. Sponsor Rep. Larry Metz, R-Yalaha, has described the bill as a preventive measure.

The same bill passed the House last year but not the Senate.
