§ 437 Singular to include the plural.

Here's a plain English summary of this rule:

This rule is about how to read the words in this section of the law. Whenever a law here uses a word in its singular form, that word also means the plural version of it. So if a law says "the person," it also covers "persons" or "people."

This matters because it stops people from arguing that a law only applies to one individual and not to a group. Lawmakers included this rule so the laws work the way they were meant to, without getting stuck on small wording issues. It keeps the focus on the actual meaning and purpose of each law, rather than technical arguments about singular versus plural language.
