law: Companies Act, 1956
  Sec 38    -     Effect
  
  of alteration in memorandum or articles.
  Notwithstanding anything in the memorandum or articles of a
  
  company, no member of the company shall be bound by an alteration made in the
  
  memorandum or articles after the date on which he became a member, if and so
  
  far as the alteration requires him to take or subscribe for more shares than
  
  the number held by him at the date on which the alteration is made, or in any
  
  way increases his liability as at that date, to contribute to the share capital
  
  of, or otherwise to pay money to, the company:
  Provided  that this section shall not apply
  
  :  
  (a) in any case where the member agrees in
  
  writing either before or after a particular alteration is made, to be bound by
  
  the alteration; or
  (b) in any case where the company is a club or
  
  the company is any other association and the alteration requires the member to
  
  pay recurring or periodical subscriptions or charges at a higher rate although
  
  he does not agree in writing to be bound by the alteration.
