Baltimore Mayor Sheila Dixon's legal bills, racked up during a years-long corruption probe that has led her to enlist seven criminal defense attorneys for a theft trial next week, could run into the hundreds of thousands of dollars, legal observers say.

Yet city residents have no idea how their elected leader plans to pay.

Dixon's chief attorneys, Arnold M. Weiner and Dale P. Kelberman, have consistently declined to explain whether they are working pro bono or how they are being compensated. The mayor, too, has been mum.

Her supporters have considered the idea of a legal defense fund, but none appears to have gotten off the ground. Even if one exists, there are few disclosure rules associated with such accounts, though city ethics rules would prevent the mayor from personally soliciting money for it.

Dixon could try to pay on her own.

The divorced mother of two, a former public school teacher, makes $151,700 as mayor.

Then there's the taxpayer option.

If Dixon were acquitted, she could submit her bills to the city Board of Estimates for repayment and argue that Baltimore should cover the legal fees of officials who have been cleared of charges. Her staff tried to put that policy on the books this year but backed off after a public outcry. Still, there's nothing that prevents her from being reimbursed.

Some close to Dixon have tried to explain her refusal to discuss the fees by arguing that jurors could be inclined to convict the mayor if they knew that, by finding her not guilty, they and other city residents would be saddled with her defense costs.

"Any decision or information on the payment of the mayor's legal bills at this time is premature and could taint the trial," said Dixon spokesman Scott Peterson. He declined to comment further.

"Hiding what's going on is actually what's drawing attention to it," said Ryan O'Donnell, director of Common Cause Maryland, a nonpartisan group that tracks the influence of money and politics. "If there were complete transparency, questions would be answered. But as it is, everyone's imagination is running wild."

Jury selection in Dixon's trial is set to begin Monday in Baltimore Circuit Court. The case, which includes seven counts of theft and embezzlement, is expected to last at least two weeks.

The city's first female mayor, Dixon, 55, was indicted in January by a city grand jury, the result of a nearly three-year state probe examining misspending at City Hall. Months later, charges were dismissed on a legal technicality, but Dixon was reindicted in July.

She is accused of purchasing personal items with retail gift cards that developers had donated for needy families while she was City Council president and mayor. She also will face a separate trial on two perjury charges stemming from gifts she received from her then-boyfriend, Ronald H. Lipscomb, a developer who was, at the same time, seeking tax credits from the city.

The mayor has denied any wrongdoing.

Dixon has assembled a seven-attorney team that, collectively, has a century and a half of legal experience. Weiner has been practicing since 1957, and Kelberman, a former federal prosecutor, is a principal at East Coast legal giant Miles & Stockbridge.

The number of lawyers involved in Dixon's defense "is not unusual in any way," Weiner said, and is necessary to counter an aggressive prosecution.

The defense attorneys, who pored through thousands of documents that "filled two huge rooms," Weiner said, will be up against four state lawyers, including State Prosecutor Robert A. Rohrbaugh. In addition, seven state investigators worked on the case, Weiner said, estimating that prosecutors have a 60 percent larger team than he does.
