WASHINGTON - Scoring a rare win over credit unions, the banking  industry persuaded a judge here to reject liberal readings of the law   requiring an institution's members to share a common bond.   
In a May 31 decision, U.S. District Court Judge John H. Pratt said the  National Credit Union Administration overstepped its authority when it   allowed Communicators Federal Credit Union to expand its membership to   anyone over 50 years old living or working within 25 miles of Houston.     
  
In the case, brought by the Texas Bankers Association in July 1994, the  judge said the agency's broad interpretation of a common bond rendered the   limitation meaningless.   
Using such standards, the NCUA "could allow those in their 20s or those  under 40 or even left-handed individuals to join credit unions merely   because people in these demographic groups allegedly share common   concerns," Judge Pratt wrote in his 15-page decision. Congress never   intended the NCUA to permit an "unguarded back door to credit union   membership."         
  
The proposed expansion could have exploded Communicators Federal's  membership by nearly half a million people - or 13 times its current size. 
NCUA General Counsel Robert M. Fenner said the agency is weighing  whether to appeal. 
This is the first such loss for the agency, which has won a string of  common-bond cases on a separate question: whether existing, though   unrelated, groups may be included in a credit union's membership base.   
  
On that question, Judge Pratt sided with NCUA in September 1994 in the  case brought by four North Carolina banks over the expansion of AT&T Family   Federal Credit Union.   
In the new case, #94-1650 at the U.S. District Court for the District of  Columbia, Judge Pratt also supported NCUA's decision to allow Communicators   Federal to add seven unrelated occupational groups. As he ruled in the AT&T   case, the judge deferred to NCUA's opinion that unrelated groups - each   with a common bond among its members - may be added to a credit union's   field of membership.         
Judge Pratt said he accepted this "multiple group policy" because courts  must defer to regulatory agencies when the law is "ambiguous." 
But Judge Pratt drew the line there, ruling - just a month after he  heard oral arguments in the case - that NCUA may not allow credit unions to   concoct a common bond.   
  
Michael Crotty, the American Bankers Association's chief litigator,  called the decision "a glorious victory" that "destroys the myth of   invincibility: The government speaks, the government wins.   
"Not anymore," Mr. Crotty said.
"The credit unions have been pushing the outer edge of the envelope,"  Texas Bankers deputy general counsel Kelly Rodgers added. "What Pratt's   ruling does is define the edge of the envelope for them."   
In this case, Communicators Federal set up a group called "Credit Union  Link" and anyone over 50 living or working within 25 miles of Houston could   join.   
The judge insisted potential members have a natural association to  qualify for the common bond exemption. 
"An association...must have a common interest, activity, or purpose  beyond that of securing access to credit unions," he wrote. 
NCUA argued that people over 50 in a particular area share common  concerns. But Judge Pratt disagreed. 
"The NCUA has attempted to justify the addition of so large and varied a  group of senior citizens on the basis of its so-called 'senior   citizen/retiree' policy," Judge Pratt wrote.   
In 1984, NCUA adopted a policy of encouraging credit unions to accept  local senior citizens. However, Judge Pratt noted that the NCUA   acknowledged then that simply authorizing federal credit unions to serve   local senior citizens "may not meet the statutory requirement of an   occupational or associational common bond."       
Communicators Federal may not accept any new 50-plus members, but the  $98 million-asset credit union will be allowed to keep the 2,500 who have   already signed up. Communicators Federal's original sponsor was   Southwestern Bell Telephone Co., but it now serves 93 different groups with   a membership of 38,283.       
Mr. Fenner praised the part of Judge Pratt's decision that upheld NCUA's  authority to allow credit unions to add other unrelated groups. 
"This policy is important to bring credit union service to more  Americans," he said. "It is also crucial to protect credit unions and   the...insurance fund by diversifying credit union membership."   
The Credit Union National Association also focused on the positive news.
"The court has again recognized that the Federal Credit Union Act was  drafted to encourage widespread credit service - not to protect banks from   competition," said CUNA president Ralph Swoboda.   
Ms. Rodgers said Texas Bankers will appeal this aspect of the decision,  hoping to convince a higher court that the NCUA should not be permitting   credit unions to accept unrelated groups.
