The District’s new ethics board, which begins its duties of monitoring ethics and investigating violations Oct. 1, announced Friday that a veteran assistant attorney general will be its first director.

Darrin Sobin, who has been an assistant attorney general for nine years, was appointed general ethics counselor by city Attorney General Irvin B. Nathan this year.

The Board of Ethics and Government Accountabilty, which held its first meeting in July, was created through legislation after criticism that the city needed to improve its ethics rules and needed a monitoring arm.

“The Director of Government Ethics plays a critical role in the successful operation of the Board. In addition to providing ethics advice and training throughout the government, the Director will lead the investigations in alleged violations of the Code of Conduct,” board chairman Robert Spagonoletti, former attorney general, said in an e-mail. “Mr. Sobin has the right combination of ethics expertise, insight into the operation of the District government, and excellent judgment to enable the Board to get off to a quick and effective start. We are fortunate to have him as the Board's senior staff member.”

Sobin has been praised for his work through the years by other attorneys general. He is the son of Dennis Sobin, a former pornography entrepreneur who ran for office several times and was convicted on federal charges of child pornography and racketeering. The father and son are estranged, leading to legal disputes in recent years.
