"Except for things that happened or didn't happen before this new law/rule/agreement came into effect."
Let's break it down:
* Except: This word signifies an exception to a general rule.
* As respects: This phrase means "in relation to" or "regarding."
* Things done or omitted to be done: This refers to actions that were taken or not taken.
* Before such supersession: This indicates a specific point in time when a new law, rule, or agreement replaced an existing one.
Here's an example:
Imagine a new law is passed that changes the speed limit on a highway. The law might include a clause saying: "Except as respects things done or omitted to be done before such supersession."
This means that:
* The new speed limit applies to all driving activities after the law comes into effect.
* Any speeding violations that occurred *before* the new law came into effect are still subject to the old speed limit and its corresponding penalties.
In simpler terms: The phrase "Except as respects things done or omitted to be done before such supersession" basically means "the new rule doesn't apply to things that already happened."
It is important to note that this phrase can have different meanings depending on the specific context in which it is used. If you encounter this phrase in a legal document, it is always best to consult with a legal professional for clarification.
