English law as the “ancestral” American legal model.
Researchers must become familiar with the research tools available in different legal systems.
The legal systems of England and Canada are most like ours, so their laws are most accessible (plus, our library has the largest holdings of these two foreign systems).
Comparative notes to remember about British legal system:
There is no written English constitution.
There is no official codification (subject arrangement) of English statutes, except through Commercial publishers (unofficial sources).
Any statute passed by Parliament is by definition valid and not subject to review by the courts. Thus, a statute’s “constitutionality” is not an issue the court can address. Only Parliament may act to change a law.
