A federal judge on Wednesday urged banking and credit  union officials to put their legal wranglings on hold until the Supreme   Court decides whether to accept a case challenging expansions by the   nonprofit financial institutions.     
"Let's give it a rest until we have seen what the Supreme Court will  do," Judge Thomas P. Jackson told officials from the National Credit Union   Administration and American Bankers Association.   
  
The Supreme Court is expected to act Feb. 14. Until then, the judge  barred both sides from filing new motions or engaging in discovery, the   fact-gathering process that precedes a trial. The judge also told the NCUA   to refrain from issuing new chartering rules.     
A federal appeals court ruled in July that all members of an occupation-  based credit union must share a single, common bond. 
  
Judge Jackson implemented that decision this fall, barring credit unions  from expanding their fields of membership and striking down interim NCUA   rules that would have permitted credit unions to serve all members of an   occupation or trade. He is expected this spring to decide whether 3,586   credit unions must divest groups that are unrelated to core members.
