NEW YORK, NY October 08, 2008 —Congressman Anthony Weiner says the move to extend term limits is vulnerable to a court challenge.

Joining him was Richard Emery, an expert on charter law. Emery says that even though it's legal for the City Council to change term limits without a public vote, it still raises ethical questions.

EMERY: It is wrong as a matter of fundamental principle that people who will have their pensions enhanced and their jobs extended are voting on their own longevity.

REPORTER: He says the mayor's bill could be seen as an abuse of power, and challenged in court for that reason.

Emery helped dissolve the city's Board of Estimate in a 1989 Supreme Court Case.
