2006 New York Code - Evidence Of When Bill Becomes A Law.

 
    § 41. Evidence  of when bill becomes a law. If a bill becomes a law by
  the approval of the governor, the certificate of the governor  shall  be
  the  evidence of the time when the bill becomes a law. If appropriations
  for the legislature or judiciary or separate items added to  a  bill  by
  the  legislature  pursuant  to  article seven of the constitution become
  part of law previously enacted by the passage of the  bill  therefor  by
  both  houses  of  the  legislature  as  provided  in such article of the
  constitution, the certificate of the governor shall be evidence  of  the
  time  when  such appropriations and added items become part of such law.
  If a bill becomes a law by the failure of the governor to sign it or  to
  return  it  to the house where it originated without his approval within
  the time required by the constitution, or if, under article seven of the
  constitution, a bill containing two or more appropriations becomes a law
  immediately as to all or as to  part  of  the  bill,  upon  the  passage
  thereof  by both houses of the legislature and without further action by
  the governor, the certificate of the secretary of state of the time when
  the bill was filed in his office shall be evidence of the time when  the
  bill,  or the part thereof not requiring further action by the governor,
  became a law.
