Expressions used in rules, bye-laws and orders to have same meaning as in Act under which they are made or issued

Expressions used in rules, bye-laws and orders to have same meaning as in Act under which they are made or issued. Where an Act, to which this Chapter applies, confers power to make rules or bye-laws or to issue orders, expressions used in such rules, bye-laws or orders, have the same respective meanings as in the Act conferring the power.
