Lawyer
A person that has been trained in the law and that has been certified to give legal advice or to represent others in litigation . Also known as a " barrister & solictor " or an attorney .

Legislation
Written and approved laws. Also known as " statutes " or " acts ." In constitutional law, one would talk of the "power to legislate" or the "legislative arm of government" referring to the power of political bodies (eg: house of assembly, Congress, Parliament) to write the laws of the land.

License
A special permission to do something on, or with, somebody else's property which, were it not for the license, could be legally prevented or give rise to legal action in tort or trespass . A common example is allowing a person to walk across your lawn which, if it were not for the license, would constitute trespass . Licenses are revocable at will (unless supported by a contract) and, as such, differs from an easement (the latter conveying a legal interest in the land). Licenses which are not based on a contract and which are fully revocable are called "simple" or "bare" licenses. A common example is the shopping mall to which access by the public is on the basis of an implied license.
