What is the main purpose behind the privileges and immunities clause of article iv?

The  privileges and immunities clause   (u.s. constitution,  article iv, section 2,clause   1, also known as the comity  clause ) prevents a state from treating citizens of other states in a discriminatory manner

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.
