I'm confident that the appellant, surgeon Jonathan Nissanoff, is an exceptionally bright person. But he's bringing an appeal on a quite complicated legal issue -- whether the Knox-Keene Act properly applies to the particular insurance company at issue in this lawsuit.
And he's doing it pro per.
I'm a reasonably intelligent person as well. But just like I wouldn't conduct surgery on myself, I'm not certain that Dr. Nissanoff should have represented himself on appeal.
