To prevent any oppression by those bye laws, it was by the same act ordained, that if any seven members of the company conceived themselves aggrieved by any bye law which should be enacted after the passing of this act, they might appeal to the board of trade and plantations (to the authority of which a committee of the privy council has now succeeded), provided such appeal was brought within twelve months after the bye law was enacted; and that, if any seven members conceived themselves aggrieved by any bye law which had been enacted before the passing of this act, they might bring a like appeal, provided it was within twelve months after the day on which this act was to take place.
