That's not quite the case in common law countries. In countries like the UK and the US, the interpretation of the law as written is ultimately decided by the court, meaning that the definition of what constitutes a crime/felony/misdemeanor is subjective. The more courts that attempt to interpret that specific law, the more 'jurisprudence' builds up, meaning that the interpretation applied in a previous decision can certainly have an impact on a future decision.
