Section" 70. The rule obtains, that the powers of municipal corporations are to be strictly construed, and any doubt or ambiguity arising out of the terms used by the legislature in making a grant of power must be resolved in favor of the public.

However, the strictness to be observed in giving construction to municipal charters should be such as to carry into effect every power clearly intended to be conferred on the municipality, and every power necessarily implied, in order to the complete exercise of the powers granted.

In the case of City of Port Huron vs. McCall, 46 Mich., 565, the court said: 'There is a principle of law that municipal powers are to be strictly interpreted and it is a just and wise rule. Municipalities are to take nothing from the general sovereignty except what is expressly granted. But when a power is conferred which in its exercise concerns only the municipality and can wrong or injure no one, there is not the lightest reason for any strict or literal interpretation with a view of narrowing its construction.

"If the parties concerned have adopted a particular construction not manifestly erroneous and which wrongs no one, and the state is in no manner concerned, the construction ought to stand. That is good sense, and it is the application of correct principles in municipal affairs."

It is held, that when a power has once been conferred, it should not be crippled or destroyed by a strained interpretation of subsequent laws.2
