Not really. Canada is federalized, but still has a unitary authority for prosecution of crimes. There are very few countries operating parallel authorities, parallel criminal courts. Most countries have a unitary authority structure with the national government being the highest source of law. The US operates a bifurcated structure where States (50+ of them) are often the final authority on criminal matters. That is strange.
Okay, fair. I meant that dual sovereignty itself isn’t strange, but I see that you meant specifically wrt criminal courts. I’ll defer to you on that since I don’t know much about it.
