A federal judge denied a series of defense motions today, clearing the way for the food stamp fraud trial scheduled to begin next Thursday against Maryland State Sen. Tommie Broadwater Jr. and four codefendants.

U.S. District Court Judge Norman P. Ramsey ruled that an address book and other papers containing references to the Prince George's County senator were properly seized by federal agents at the Landover home of codefendant William Dudley, 49. The judge also turned down requests to have the five defendants tried separately.

Broadwater, 41, his daughter, Jacqueline, 21, and the other defendants were indicted in April on charges of laundering $70,000 in illegally obtained food stamps through Broadwater's Fairmont Heights supermarket.

Prosecutors said a Secret Service agent posing as a food stamp thief sold $70,000 in marked food stamps for 40 percent of their face value to Dudley and two other Broadwater associates, Raymond James Quigley Sr. 68, his son, Raymond Jr., 49.

Dudley then allegedly transported the food stamps to Broadwater, who in turn paid Dudley 60 percent of their face value. Broadwater allegedly processed the stamps through his market, with daughter Jacqueline devising "fictitious internal documents" to conceal their illicit origin. Prosecutors said Broadwater redeemed some of the stamps from the government for full value.

Judge Ramsey rejected arguments by Dudley's attorney that Secret Service agents searching his house improperly seized an address book containing Broadwater's name and papers bearing his initials and telephone numbers.
