The California Lawyer Magazine holds an Extreme Advocacy Contest. The problem is to argue a seemingly ridiculous point so as to convince your audience.
The winner, Blair Hoffmann, argued that the same lawyer should represent both sides on appeal. Others argued that the moon is made of green cheese, people should walk on all fours, and Queen Elizabeth is the reigning monarch of the USA. The competition was judged by Alex Kozinski, a judge on the Ninth Circuit.
bq. Having the same attorney represent both parties (1) enhances the quality of the advocacy, (2) is fairer, and (3) is more efficient. I do not advocate that the same attorney must represent both parties-on occasion multiple attorneys might be useful-but courts should permit, even encourage, a single attorney to represent both sides. Ethical obligations, properly understood, do not stand in the way.
