(a) No supervisor shall evade the provisions of section 3101¹ as to advertising for bids by purchasing or contracting for services and personal properties piecemeal to obtain prices under the required advertising price. This provision is intended to make unlawful the evading of advertising requirements by making a series of purchases or contracts each for less than the advertising requirement price, or by making several simultaneous purchases or contracts each below the required advertising price, when the transactions involved should have been made as one transaction for one price. Any supervisors who vote in violation of this provision and who know that the transaction upon which they vote is or ought to be part of a larger transaction and that it is being divided in order to evade the requirements as to advertising for bids are jointly and severally subject to surcharge for ten percent of the full amount of the contract or purchase.

(b) Any supervisor who votes to unlawfully evade the provisions of this article and who knows that the transaction upon which he so votes is or ought to be a part of a larger transaction and that it is being divided in order to evade the requirements as to advertising for bids commits a misdemeanor of the third degree for each contract entered into as a direct result of that vote. This penalty shall be in addition to any surcharge which may be assessed pursuant to subsection (a).
