Note the BYU logo behind Mr. Hatfield. Apparently he was a BYU undergrad and a Texas Austin law grad. Poor guy.

Social Security claimants lawyer Chad Hatfield didn’t realize his goof until several minutes into an argument last Monday before the 9th U.S. Circuit Court of Appeals at San Francisco. Hatfield, a lawyer from Washington, was talking about fibromyalgia symptoms when judges said they were looking at a case concerning diabetes, manic-depressive disorder and social phobia.

“Check to make sure you’ve got the right case in front of you,” said one of the judges.

At that time—about five minutes and 10 seconds into the video—Hatfield realized that he was arguing the wrong case.
