law: Sashastra Seema Bal Act, 2007 
  70.  Duty of commanding officer in regard to
  
  detention.
  1.       It
  
  shall be the duty of every commanding officer to take care that a person under
  
  his command when charged with an offence is not detained in custody for more
  
  than forty-eight hours after the committal of such person into custody is
  
  reported to him, without the charge being investigated, unless investigation in
  
  the prescribed procedure, within that period seems to him to be impracticable
  
  having regard to the public service.
  2.       The
  
  case of every person being detained in custody beyond a period of forty-eight
  
  hours, and the reasons therefore, shall be reported by the commanding officer
  
  to the next higher officer or such other officer to whom an application may be
  
  made to convene a Force Court for the trial of the person charged.
  3.       In
  
  reckoning the period of forty-eight hours specified in sub-section (1) ,
  
  Sundays and other public holidays shall be excluded.
  4.       The
  
  manner in which and the period for which any person subject to this Act may be
  
  taken into and detained in Force custody, pending the trial by any competent
  
  authority for any offence committed by him, shall be in such manner as may be
  
  prescribed.
