Expert writing Tips
Best practice
Ensure the antecedent (the noun before 'that') is singular; if you are discussing multiple laws, you must use "that authorize" instead.
Common error
Writers sometimes use "that authorizes" when they actually mean that something is required. Authorization implies that an action is permitted or made legal, but it does not necessarily mean it must happen. If an action is compulsory, use "that mandates" or "that requires".

Ludwig's WRAP-UP
The phrase "that authorizes" is a robust and grammatically correct tool for describing the conferral of power or permission. Ludwig AI data confirms its high frequency in authoritative domains like The New York Times and various legal databases, where it is used to precisely define the scope of bills, warrants and regulations. It is essentially the 'gold standard' for formal writing when one needs to explain what a particular document allows a person or entity to do. When using this phrase, ensure that your subject is singular and that you are specifically discussing permission rather than a mandatory requirement. For plural contexts, simply shift to the plural form "that authorize".
