Art. 7 Municipal and parochial officers included

This rule says that certain job titles used in the criminal procedure laws should be read broadly. When the law mentions a "district attorney," that also means a city prosecutor. When it mentions a "sheriff," that also covers a police chief or city marshal. The same idea applies to other official titles too. They include the local city or parish version of that job, not just the main one.

The point of this rule is to keep things simple. Instead of rewriting every law to list every possible local official by name, the law just uses one general title and lets it stand in for similar jobs at the city or parish level. This only changes if the context of a specific law makes clear that it means something different.

For someone involved in a criminal case, this matters because it means local officials, like a city police chief or a city prosecutor, have the same authority and responsibilities as their counterparts named in the law. You cannot argue that a rule does not apply just because it says "sheriff" or "district attorney" instead of naming your local official directly.
