 This rule disallows strict mode directives, no matter which option is specified, in functions with non-simple parameter lists (for example, parameter lists with default parameter values) because that is a syntax error in **ECMAScript 2016** and later. See the examples of the [function](#function) option.
 
+This rule does not apply to class static blocks, no matter which option is specified, because class static blocks do not have directives. Therefore, a `"use strict"` statement in a class static block is not a directive, and will be reported by the [no-unused-expressions](no-unused-expressions.md) rule.
+
 The `--fix` option on the command line does not insert new `"use strict"` statements, but only removes unneeded statements.
