  45. Petition where person whose consent
  
  is necessary is insane, or unjustly withholds consent
  If any person whose
  
  consent is necessary to any marriage under this Part is of unsound mind, or if
  
  any such person (other than the father) without just cause withholds his
  
  consent to the marriage, the parties intending marriage may apply by petition,
  
  where the person whose consent is necessary is resident within any of the towns
  
  of Calcutta, Madras and Bombay, to a Judge of the High Court, or if he is not
  
  resident within any of the said towns, then to the District Judge :
  Procedure on petition
  And the said Judge of
  
  the High Court, or District Judge, as the case may be, may examine the
  
  allegations of the petition in a summary way ;
  and, if upon
  
  examination such marriage appears proper, such  Judge of the High Court or
  
  District Judge, as the case may be, shall declare the marriage to be proper
  
  marriage.
  Such declaration shall
  
  be as effectual as if the person whose consent was needed had consented to the
  
  marriage
  and if he has
  
  forbidden the issue of the Marriage Registrar’s certificate, such certificate
  
  shall be issued and the like proceedings may be had under this Part in relation
  
  to the marriage as if the issue of such certificate has not been forbidden.
