Most appellate courts have rules limiting the number of pages or words in a brief. When a brief is a bit too long, lawyer-editors have a number of techniques for making the brief fit the applicable limit. Some are good. Others are not so good.
An example of the latter comes from the Federal Circuit’s decision last spring in Pi-Net International, Inc. v. JPMorgan Chase & Co., No. 2014-1495 (Fed. Cir. Apr. 20, 2015), cert. denied sub nom. Arunachalam v. JPMorgan Chase & Co., No. 15-691, — U.S. — (Jan. 11, 2015) (PDF copy here). There, the appellants decided to squeeze their brief under the 14,000-word limit by removing the spaces between words. For example, instead of providing this citation:
Thorner v. Sony Computer Entm’t Am., LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012) [14 words]
they provided this one instead:
Thorner.v.SonyComputerEntm'tAm.LLC,669F.3d1362,1365(Fed.Cir.2012) [1 word].
