(a) An employer who is delinquent in his contributions shall be liable to the System for the benefits which may have been paid by the System to his employees or their dependents, and any benefit and expenses to which such employer is liable shall constitute a lien on all his property, real or personal, which is hereby declared to be preferred to any credit, except taxes. The payment by the employer of the lump sum equivalent of such liability shall absolve him from the payment of the delinquent contribution and penalty thereon with respect to the employee concerned.
(b) Failure or refusal of the employer to pay or remit the contribution herein prescribed shall not prejudice the right of the employee or his dependents to the benefits under this Title. If the sickness, injury, disability or death occurs before the System receives any report of the
name of his employee, the employer shall be liable to the System for the lump sum equivalent to the benefits to which such employee or his dependents may be entitled.
