What’s the difference between objecting and excluding myself from the settlement? Objecting simply means telling the Court that you don’t like something about the settlement.

If you exclude yourself, you have no basis to object because the case no longer affects you. THE COURT’S FINAL APPROVAL HEARING 20.
