ALBANY – A top state lawmaker dealt another blow to New York City’s Olympic hopes yesterday by suggesting for the second time in a week that a public meeting be held on whether to approve a proposed $2 billion stadium in Manhattan that many have described as a prerequisite to winning the bid to host the 2012 Summer Games.

The majority leader of the Senate, Joseph Bruno, a Republican of Rensselaer, said last week that proponents and opponents of the 75,000-seat domed stadium should make their case in a public setting. Governor Pataki, a backer of the project, responded that all questions relating to a $300 million state subsidy have already been addressed.

Yet Mr. Bruno made clear again yesterday he remains unsatisfied with the answers he has received on questions ranging from the shared use of convention space at the site to the way in which the state-subsidized bonds would be repaid. The New York Jets recently won a $250 million bid to build the proposed football stadium on a platform over 13 acres of rail yards of the Metropolitan Transportation Authority.

“We’re waiting still to get clarity on some of the answers on questions that we’ve asked that pertain to the stadium and the ramifications of it,” Mr. Bruno said. “I can’t make that decision yet. I still believe that the most productive thing that can happen for this city and the state is to have a public meeting with the governor, the mayor, the speaker, and myself, and anyone else that we need to have an intelligent discussion as to the best use of that site over the MTA yards.”

Mr. Bruno and the Assembly speaker, Sheldon Silver, a Democrat of Manhattan, each controls one of the three votes on the Public Authorities Control Board, a state panel which approves the issuance of bonds for public projects. The two men have tabled votes on the project twice in the past week. Both legislative leaders have also said lawsuits relating to the competitiveness of the Jets’ bid should be resolved before a vote on the stadium subsidy is held. Madison Square Garden, owned by Cablevision, has filed a suit saying the award of the development rights to the Jets was rigged. Mr. Bruno’s son, Kenneth, is a lobbyist for Cablevision.

Mr. Pataki, who controls the third vote on the control board, and Mayor Bloomberg have said the stadium subsidy must be approved before the International Olympic Committee decides July 6 on a host city for the 2012 Olympics. The chairman of the U.S. Olympic Committee, Peter Ueberroth, said the same in a May 5 letter he sent to Messrs. Bruno, Silver, and Pataki. That letter was leaked to the press last Thursday.

Mr. Bruno said yesterday he is preparing a response to Mr. Ueberroth that would outline his commitment to build an appropriate Olympic facility if New York is chosen as the host. He said the letter would probably go out this week. The next regularly scheduled board meeting is in June, though Mr. Pataki may call a special meeting before that in an effort to force a vote.

“We have said repeatedly that if the Olympics vote to come, and I hope they do, we will build whatever facility it takes to meet the requirements of the proposal that was made,” Mr. Bruno said. “We will vote in the Senate to support the Olympic bid. I am going to get a letter out as a matter of fact to the chair of the Olympic committee emphasizing that – that if they vote to come we will build specifically what it is that meets the requirement of the proposal.”

Asked yesterday if he agreed with Mr. Bruno on the need for public hearings, Mr. Silver said: “Absolutely. Whatever he says.”
