N.J. Stat. Ann. § 19:44A-20.9

8. If a business entity makes a contribution that would cause it to be ineligible to receive a public contract or, in the case of a contribution made during the term of a public contract, that would constitute a violation of this act, the business entity may request, in writing, within 60 days of the date on which the contribution was made, that the recipient thereof repay the contribution and, if repayment is received within those 60 days, the business entity would again be eligible to receive a contract or would no longer be in violation, as appropriate.
