Chap. 145. An Act validating a certain license granted by the department of public works to maco development CO., INC. Whereas, The deferred operation of this act would tend to defeat its purpose, which is to perfect the title to certain land in order to facilitate forthwith the construction of certain taxable property thereon and thereby contribute to the industrial development of the commonwealth, therefore it is hereby declared to be an emergency law, necessary for the immediate preservation of the public convenience. Be it enacted, etc., as follows: License numbered 5074 granted by the department of public works to Maco Development Co., Inc. on June eighth, nineteen hundred and sixty-six and made irrevocable by chapter five hundred and ninety-four of the acts of nineteen hundred and sixty-six shall, notwithstanding the failure to record said license within one year as required by section eighteen of chapter ninety-one of the General Laws, be as valid and irrevocable as if said license had been recorded in compliance with the provisions of said section. Approved April 10,1968.
