Tag they were served notice of appeal

A legal term!

"Tag they were served notice of appeal" is a phrase that means "they were served with a notice of appeal". In other words, a party (in this case, "they") was formally notified that an appeal is being filed against a decision or judgment made in a court case.

Here's a breakdown of the phrase:

• "Tag" is an old-fashioned term for "serve" or "deliver". It's thought to have originated from the practice of attaching a document to someone's clothing or hat, like a "tag" or a label.
• "They" refers to the party being notified of the appeal.
• "Were served" means that the notice of appeal was formally delivered to the party.
• "Notice of appeal" is a formal document that initiates the appeal process. It typically includes details about the appeal, such as the grounds for the appeal, the court to which the appeal is being made, and the deadline for filing the appeal.

So, when someone says "tag they were served notice of appeal", they're simply saying that the party was formally notified that an appeal is being filed against a previous court decision.
