An Arlington judge declined yesterday to consider a plea from former congressional lobbyist and Playboy model Paula Parkinson who is seeking court-ordered support from her estranged husband and one-time business partner.

Juvenile and Domestic Relations Court Judge Burton V. Kramer dismissed Parkinson's petition, saying his court, which hears a variety of marital and juvenile disputes, lacked jurisdiction in the case.

Parkinson, who gained widespread notoriety after claiming she had videotaped Republican congressmen in her bedroom while she was lobbying against a crop insurance bill, sued her husband, Hank Parkinson, claiming she needed help in meeting more than $3,000 in monthly expenses and "assorted staggering bills."

Lawyers representing her said they were surprised by the judge's action. "I was perplexed," said attorney Glenn Lewis. "At the hearing last month [when the case was first introduced] he never mentioned there was a problem."

Lewis said Parkinson plans to press her appeal, either in a higher court in Arlington or in D.C. Superior Court. "He's not supporting her at all. She has to seek remedy somewhere," Lewis said.

Paula Parkinson's activities aroused concern on Capitol Hill this spring when several House members acknowledged having spent a golfing weekend with her in a Florida cottage. Currently she is seeking a publisher for a book in which she says she will name all but a few of the government officials with whom she has shared beds during recent years.

Hank Parkinson, a former journalist involved in both the lobbying efforts and the couple's earlier attempts to market diet pills, has called his wife's claims for support "ludicrous," saying the news of her alleged affairs with various U.S. representatives "ruined" his public relations business.

He has filed for divorce in the District of Columbia on grounds of adultery.
