For David Paterson, Next Stop: M.T.A. Over the years, the Metropolitan Transportation Authority board has had among its members its share of lawyers, failed mayoral candidates, union leaders - even the wife of a former Beatle. So while it may be hard to top the star power of Nancy Shevell, who left the board this year after she married Paul McCartney, the board did make history on Monday by appointing a former governor as her replacement: David A. Paterson. Gov. Andrew M. Cuomo announced on Monday that he appointed his predecessor to replace Ms. Shevell, an executive in the trucking industry. It was unclear when Mr. Paterson will join the board; his appointment, which was first reported by The Daily News, must still be confirmed by the State Senate. The governor was asked at a news conference why he chose to "reward" Mr. Paterson with a position on the board. Mr. Cuomo emphasized that the position was unpaid, and in any case, Mr. Paterson had the expertise to be a "powerful advocate and informed voice." Mr. Cuomo said that Mr. Paterson "understands how the Legislature works, he understands how budgets work, he understands the political process." The authority's chairman, Joseph J. Lhota, also praised Mr. Paterson for his long career in politics, adding that he has known Mr. Paterson for 35 years. "Former Governor Paterson will bring a unique and practical perspective, particularly with respect to issues affecting minority communities and disabled New Yorkers," Mr. Lhota said. Mr. Paterson's appointment was reported by The Daily News. As governor, Mr. Paterson appointed Mr. Lhota's predecessor, Jay H. Walder, and also oversaw the board for two fare increases. Transit advocates said they hoped that Mr. Paterson's background could help him find alternatives to future fare increases. "If anyone knows New Yorkers are tired of paying more for less and how to find fairer ways to invest in transit, it's David Paterson," Paul Steely White, executive director of the advocacy group Transportation Alternatives, said.
