Is paying money to technical inspection agents to obtain a certificate allowing a car to be driven, knowing that there are defects and that they are demanding a bribe, considered a bribe?

What is paid to obtain a right or to avert injustice is not considered a forbidden bribe for the payer if he cannot obtain his right otherwise; the sin then lies with the recipient of the bribe. As for the forbidden bribe, it is what is paid to invalidate a right or to establish falsehood, or what is paid without compelling necessity when one is able to obtain the right without a bribe. So, if the car is entitled to a roadworthiness certificate and the officials are obstinate, and the questioner finds no alternative but to pay a bribe to obtain his right, there is no sin upon him. However, if the car has a defect that prevents it from obtaining the certificate, then paying the bribe is forbidden, because through it one obtains what he is not entitled to.
