Are checks issued as an evidence of debt covered by BP 22?

Yes. A check issued as an evidence of debt, though not intended for encashment, has the same effect like any other check. It is within the contemplation of B.P. 22, which is explicit that “any person who makes or draws and issues any check to apply for an account or for value, knowing at the time of issue that he does not have sufficient funds in or credit with the drawee bank which check is subsequently dishonored shall be punished by imprisonment.
