The notice shall also state that the church or school has the right to object under section sixteen C to the issuance or transfer of the brewery license. If the authorities in charge of any such school or church complain to the commission in writing that a brewery license has been issued or transferred without the mailing of the requisite notice, and that they object to such issuance or transfer, the commission shall hold a hearing to determine whether the requisite notice was mailed. If after a hearing the commission determines that notice was not mailed as required, then the commission shall cancel the farmer-brewery license unless, such school or church had actual notice, prior to issuance or transfer, of the application and of the right to object under said sixteen C, or such school or church did not complain as soon as possible after actual notification of the application and of the right to object.
Any farmer-brewer aggrieved by the cancellation of his license or any school or church aggrieved by the commission's refusal to cancel such a license may appeal as provided herein.
For the above purposes, a barrel shall be thirty-one gallons.
