Lawyers for former Washington Teamster official Frank DeBrouse yesterday filed documents in U.S. court in Baltimore answering many of the charges of a 15-count indictment that alleged that DeBrouse received at least $200,000 in gifts from local corporations that wanted to ensure labor peace.

DeBrouse stated in the documents that several of the key participants in the alleged transactions cited in the indictment have given his lawyers accounts that conflict with the charges in the indictment.

He asked that most of the counts of the indictment be dismissed.

The documents also charge that the government "improperly abused the grand jury process" to aid Daniel George, De Brouse's successor as head of Local 639, in civil lawsuits against DeBrouse. George headed a dissident slate that defeated DeBrouse in 1977 to take charge of Washington's largest Teamsters local.

Russell T. Baker Jr., U.S. attorney for Maryland, responded toDeBrouse's charges yesterday by saying "The grand jury process in this as in all cases was used solely and strictly for the purpose of investigating and prosecuting federal criminal offenses."

In the indictment last October, Excavation Construction Inc., a multimillion-dollar Prince George's County firm, headed by John W. Lyon, was accused of giving DeBrouse the most expensive favor -- $145,000 in labor and material to build DeBrouse's home in Anne Arundel County.

The indictment charged that the house cost about $280,000 but that DeBrouse paid $135,000.

In his sworn statement filed yesterday DeBrouse states that he believes Lyon testified before the grand jury, but the Lyon's testimony would have merely established that there was a dispute between John Lyon Inc. and DeBrouse over the true cost of the home. The matter resulted in a lawsuit between DeBrouse and Lyon Builders Inc.

DeBrouse's filings do not make clear the basis for his statements about Lyon's alleged grand jury testmony.

Lyon, reached yesterday by phone, declined to comment.

DeBrouse also was charged in the indictment with extorting $19,000 worth of architectural services and $10,388 worth of carpeting from Giant Food Inc.

DeBrouse in his sworn statement asserts that two Giant officials, Israel Cohen and Alvin Dobbin, have denied in the presence of DeBrouse and his lawyers, that DeBrouse ever "directly or indirectly induced Giant Food Inc. to do any act by the wrongful threat and use of fear of financial or economic injury."

DeBrouse also was charged with receiving through two intermediaries -- defined in this case as men representing DeBrouse -- cash payments of $10,000 from Pinto Trucking Services Inc. and of $9,000 from Pinto president Rovert Pinto. DeBrouse also was charged with receiving through an intermediary $200 weekly payments from Robert Pinto from November 1973 to December 1974.

Vincent Caprio, who according to the indictment allegedly received the $10,000 payment and the weekly payments on behalf of DeBrouse, had denied to DeBrouse's attorneys that he ever stated he was a "nominee" of DeBrouse, according to DeBrouse's sworn statement.

The sworn statement also asserts that Robert Donkis, who, according to the indictment received $9,000 as a nominee for DeBrouse, has "categorically denied" that he accepted any money from Pinto Trucking on DeBrouse's behalf.

The indictment also charged that DeBrouse attempted to extort $1,771 worth of cement from Contee Sand and Gravel Co. of Laurel and $2,200 worth of appliances from Joseph M. Zamoiski Co., an appliance wholesaler.

In their answer to the indictment charges of tax evasion, DeBrouse's lawyers allege that the government bypassed Internal Revenue procedures enacted to protect citizens before criminal proceedings are started against them.

They also charged that these tax evasion counts of th indictment should be dismissed because they are unconstitutionally vague.

The indictment returned last October was the result of almost two years of investigations into alleged albor management recketeering in the Baltimore and Washington areas.
