§ 133.520 [Amended by 1965 c.508 §2; 1973 c.836 §75; renumbered 133.450]

This rule doesn't actually contain any current legal content. It shows a history of changes made over the years, and it tells us the rule was eventually renumbered as 133.450.

If you're trying to find the actual law that applies to your situation, you'll need to look up Rule 133.450 instead. That section will have the current text and requirements that replaced this one. Laws get renumbered sometimes as legislators reorganize sections, so the content didn't disappear, it just moved to a new location in the code.
