A by-law (also spelled bylaw or bye-law) is a rule or law established by an organization or community to regulate itself, as allowed or provided for by some higher authority. The higher authority, generally a legislature or some other government body, establishes the degree of control that the by-laws may exercise. By-laws may be established by entities such as a business corporation, a neighborhood association, or depending on the jurisdiction, a municipality.
Corporate and organizational bylaws regulate only the organization to which they apply and are generally concerned with the operation of the organization, setting out the form, manner or procedure in which a company or organisation should be run. Corporate bylaws are drafted by a corporation's founders or directors under the authority of its Charter or Articles of Incorporation.
