Explain the theory of virtual representation in your own words. Was it valid?

The concept of virtual representation held that people like the American colonists did not need to be able to elect their own representatives to Parliament. The theory held that the members of Parliament already represented everyone in the British Empire. They did not just represent the people who elected them.

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
