Answer:
if you are asking who should prevail in this scenario, its most likely the mechanics.
Step-by-step explanation:
first off, its the fleet owner who has taken the cabs to that certain mechanic,
therefore he is responsible for the first move, but on the other hand, the mechanics shouldnt be working on cars like taxicabs in the first place with out a license if they DIDNT have one in this case. if they didnt then they would be the ones most likely to lose the case. and another reason, the mechanics knew what theyre doing but never hesitated on switching plans for other brake parts. so in this case, its the mechanics who should prevail.
