On the check page Loupe drafts the statement for this court from the parts you tick, for you to read and sign: what it says is your choice and your responsibility. The order in force on the day is what counts; read it at the source before relying on this page.

Check the filing first

Paste the brief or drop the file, and Loupe looks up every citation in the published record: whether the case exists, whether it is the case the filing names, whether the pin cite falls inside the opinion; statutes, regulations, court rules and links too. It doesn’t generate anything, and what it can’t settle it marks “not verified”, never clean.
