Plainfield resident Ed Brown, who along with his wife was convicted of multiple felony tax evasion charges this week, said yesterday he and a group of legal analysts are preparing to take legal action "to nullify the whole problem."

"We're working on legal matters and actions," Brown said during a telephone interview. "This court is totally off the wall for its actions, and the record will show that clearly."

Believing he would not get a fair trial because, among other reasons, the federal court and his accuser are the same entity, Brown hasn't left his house for about a week and was not in court for the conclusion of his or his wife's trial. Dr. Elaine Brown, however, was in court when the verdict was read Thursday and is now under electronic surveillance at her son's home in Massachusetts.

"The jury was rigged before they were there, the jury was rigged before they went out, and now my marriage is destroyed," Ed Brown said, clarifying that there has been no talk of divorce.

The Browns argue that there is no law that requires them to pay federal income tax and that the federal government has no jurisdiction in New Hampshire. The couple does pay local, school and county taxes, Ed Brown said.

Although rejected by the courts, the Browns' arguments has struck a chord with some. Supporters of their cause have gathered at the end of the driveway that leads to the Browns' house, a concrete-walled structure that, at least for now, doubles as a prison, Brown said.

"I don't want to hurt anybody, so I'm staying here - right now, but we're working on that."

The U.S. Marshal's Office in Concord has indicated there are no plans to storm Brown's house to arrest him.

The media attention to the Browns' now high-profile case has sparked the interest of legal analysts from across the country, Brown said.

"They're stunned that the judge had the audacity to just dismiss everything offhand," he said. "He violated so many due processes it's incredible."

Brown, a member of the United States Constitution Rangers, refused to disclose what type of action he might take, but said his "mistake" during the recent court proceedings was filing more than 40 motions in the case, all of which were dismissed.

"We used motions in their court; that's their method and way," he said. "We should have used affidavits because the judge has to respond lawfully to affidavits. That's where we made the mistake. But that's OK; there's still room.

"We're going to be working on something pretty soon to nullify the whole problem," he said.

Brown, 63, has been convicted of one count of conspiracy to defraud the federal government and one count of conspiracy to structure financial transactions.

Dr. Brown, 65, has been found guilty of one count of conspiracy to defraud the federal government, one count of conspiracy to structure financial transactions, five counts of federal income tax evasion, eight counts of failing to collect federal payroll taxes for employees in her Lebanon dental office, and two substantive counts of structuring.

The Browns each face five years' imprisonment for each of the counts of conviction, except for the structuring charges, which carry a maximum penalty of 10 years. Each conviction also carries a fine of up to $250,000. The U.S. Attorney's Office said the sentence is likely to be less than the maximum.

The Browns are both scheduled for sentencing April 24.
