(a) re-open any transaction, or any account already taken between the parties ;
(b) take an account between the parties ;
(c) reduce the amount charged to the debtor in respect of any excessive interest ;
(d) if on taking accounts it is found that the money-lender has received more than what is due to him, pass a decree in favour of the debtor in respect of such amount :
Provided that, in the exercise of these powers, the Court shall not,-
(i) re-open any adjustment or agreement purporting to close previous dealings and to create new obligations which have been entered into by the parties or any person through whom they claim at a date more than six years from the date of the suit to which this Act applies ;
(ii) do anything which affects any decree of a Court.
