§ 136.550 [Amended by 1973 c.836 §239; renumbered 136.440]

This rule doesn't have any real content to summarize. It shows that the law was changed back in 1973 and later given a new number: 136.440. If you want to know what this rule actually says, you'll need to look up 136.440 instead, since that's where the current version lives.

Renumbering like this happens sometimes when lawmakers reorganize the legal code. The rule itself didn't disappear. It just moved to a new spot and probably got folded in with related rules. So if you're researching this topic, always check the new number to get the accurate, up-to-date text.
