Alan Zegas, an attorney for Wildstein, filed a motion on Wednesday to quash the subpoena compelling Wildstein to testify before the New Jersey Assembly Transportation Committee.
Zegas said the subpoena was invalid for a number of reasons. His first reason: He doubts whether John Wisniewski, the chair of the Assembly Transportation Committee, actually signed the subpoena.
"There is significant evidence to believe that Mr. Wisniewski did not actually sign the documents, creating doubt about their validity," Zegas wrote in the filing.
Zegas went on to analyze Wisniewski's signature in two other documents — the letter accompanying the subpoena and his financial disclosure form. He opined that all three were different.
Zegas also wrote that the subpoena should be "unenforceable," because it is "exceedingly unusual for a New Jersey Legislative Committee to issue investigative subpoenas." According to the motion, only four subpoenas have been issued over the past two decades.
And Zegas claimed that Wisniewski has a conflict of interest — his law firm has represented a construction and marine dredging firm that had a contract with the Port Authority.
