They have to acknowledge that the rule exists, and then deliberately break it, because their task takes priority over the rule.

If the question is "does this break the rule?" then the answer is "yes, but". If the question is "will it stay out of the park?" then the answer is "no". The real world doesn't work exactly like if (cond) statements in code.
