Any POA in general will have following line;
All the acts lawfully done B in pursuance to this POA shall stand ratified by A......
So it is clear that A does not take any explicit responsibility for any unlawful acts of B, thats where the question of vicarious liability comes
into picture. The honorable SC, while hearing a case of multiple directors brought into the folds under S.138, expressed caution that in order
to even fix (and to start the process) the complainant has to specifically allege the involvement of such directors, mere statement alone is
not sufficient. That means SC has not accepted the blind role of vicarious liability with respect to criminal matters. So the statement above by
Mr Sumitra Kumar that master must be responsible for the acts of .... has to be analysed carefully
Ex1: "B" creates some liability in the normal course of business under POA and runs away: "A" is responsible to settle the same.
Ex2" "B" binds A in some contract under this POA : "A" has to honor the contract.
Ex3: "B" deposes falsely infront of court under this POA for some case. " B" may face perjury, not A.
Ex4 Cheque signed by "B" for discharge of liability created in normal course under POA bounces"
This will answer your question: A is responsible to settle this liability, he cannot run away from the liability if pursued, but criminality aspect cannot
be put on 'A" vicariously. That means 'A" if gets dragged then he can prove that he was not involved in the issuance of cheque. So, you can pursue the criminal case under S.138 against B itself, but if you wish to file a civil recovery case you must involve both A and B.
