A promised investigation into a Washington Post account of sexism in the Virginia General Assembly died today after its sponsor found his proposal blocked by objections from a woman legislator.

Del. Warren Barry (R-Fairfax) said today there was "no point" in trying to introduce the measure because he did not have the unanimous approval of the House of Delegates.

Under House rules, Barry needed unanimous approval to introduce such a measure because the regular deadline for introducing legislation has passed. a voice vote by the House Monday seemed to give him that endorsement, but Del. Dorothy McDiarmid (D-Fairfax) has claimed that her vote of opposition had not been counted because she spoke too softly.

Barry said today he had not changed his opinion of the Post article, which he had criticized as "fiction" in a floor speech a day after the article appeared. Barry promised to introduce legislation next year calling for the creation of an ethics committee to investigate alleged wrongdoing by legislators.

Although Barry said he had not consulted McDiarmid before she registered her opposition to his measure, some legislators speculated that Barry was relieved at being freed of the responsiblity of pressing for what many said would have been a time-consuming and unpopular investigation .
