COLUMBIA, S.C.  – A legislative initiative aimed at preventing  “a court or other  enforcement authority” from enforcing foreign law in  the Palmetto State  was introduced today in both the S.C. House and  Senate by Rep. Wendy  Nanney (who drafted the bill) and Sen. Mike Fair  respectively, who say  the bill will preempt violations of a person’s  constitutional rights  resulting from the application of foreign law. 
Legislators  and other proponents of the bill say America has unique  values of  liberty which do not exist in foreign legal systems. Yet  foreign laws  are increasingly finding their way into U.S. court cases,  particularly  in the area of family law, involving divorce and child  custody where,  for instance, Islamic Shariah Law has been invoked in  several U.S.  states. 
I have worked briefly with  Wendy Nanney, and I know that she is a conscientious politician. Her  comments about Sharia law almost got her a 
Tancredo Award, but nevertheless, the actual bill is a much better one that what we saw in 
Oklahoma.  By broadening the language of the bill to restrict any type of foreign  law, conservatives appear more consistent in their beliefs.
They  also refrain from singling out scary ethnic groups (although Nanney  still got in a lick). There is no reason to pinpoint Sharia Law, because  despite what Newt Gingrich thinks, there is no threat from secret  Muslim conspirators who want to take over American courts. All together  we can 
cite one  criminal case where "Sharia Law" was invoked by a judge in New Jersey.  His decision was later reversed and rightfully so. Yet, if Newt (and  Nanney) is concerned about the use of arbitration in civil cases, then  he ought to pick on the Jewish community, who daily are allowed to go  before the 
beit din (rabbinic law court) to arbitrate "real estate deals, nasty divorces, and business disputes."
Of  course, we all know that Newt and company aren't going to lead a  crusade against the radical imposition of rabbinic law. There are no  quality political points to be had in attacking God's people. Muslims,  on the hand, are open season.
In the end, there are  profound reasons why conservatives should guard against foreign law. But  let's throw up a wall against all foreign law (see South Carolina  bill), instead of smiling in the camera as we bash Islam (see Oklahoma  law).
