the problem with Roman-Napoleonic systems is that this will let you find changes to articles in law codes, but large swathes of the law are just declared out of context, and its interaction with the rest of law is for lawyers and judges to interpret - which is what makes them inherently different to case law systems

note that even in case law systems, legislators can still pretend to be clarifying or reinterpreting things to essentially change law, but at least the supposed principle is that law has to stay coherent and go through all the pertinent checks and balances

in the UK legislation traces back to its origin, with all relevant amendments, see for example:
