2006 New York Code - Instruction.

 
  Section 8--305. Instruction.
    (a) If an instruction has been originated by an appropriate person but
  is  incomplete  in  any  other  respect,  any  person may complete it as
  authorized and the issuer may rely on it as completed,  even  though  it
  has been completed incorrectly.
    (b) Unless  otherwise  agreed,  a  person  initiating  an  instruction
  assumes only the obligations  imposed  by  Section  8--108  and  not  an
  obligation that the security will be honored by the issuer.
