rest my case

[CW Tan]

Hi teachers,

I wonder if there is such a phrase as "I will rest my case", which seems to mean "I have no comments to make on a certain matter" or "I don't want to make any comments".

Thank you very much in advance.

That's what I've found in web concerning your question:

I rest my case
- you have proved that what I just said is true. Ned's mother said he needs to leave home or he'll never be independent. His sister said, “But he can't even do his wash!” and his mother replied, “I rest my case.”

"What you've just said proves my point" - I think that explains the phrase in a clearest way.

Good luck!
