A refused to register the marriage of B and C to enter their marriage in the register unless he was paid 50.B paid the money
It was A's duty to register the marriage of B and C, but he unlawfully insisted on doing so only if he was given $50.
Under pressure, B handed over the money for the registration.
A's claim was an abuse of office and included economic pressure because B had no genuine option.
The payment was not legally due, and B would be able to recover the money.
A could also be subject to disciplinary or criminal charges for his conduct.
