Cathy Gellis, guesting at Popehat, has a long post on the latest in the Prenda Law saga. A relevant paragraph:
The default rule in American litigation is that everyone pays for their own lawyers. But some laws, the Copyright Act being one of them, have provisions so that the loser pays for both sides’ lawyers. … But just because a judge may grant an award of attorney fees doesn’t mean the money will ever be recovered; enforcing a judgment often presents its own expensive challenges, meaning a wronged defendant can still be saddled with the costs of his own defense. However the California Code of Civil Procedure has a provision, § 1030, to help mitigate that financial risk by allowing defendants in similar positions as Mr. Navasca [a man seeking fee recovery from Prenda Law over a questionable copyright action] to require plaintiffs to make an “undertaking;” that is, to post a bond that would guarantee, when the defendant inevitably wins his fees, that he would actually get the money.
Both provisions could prove important in bringing the rogue legal enterprise to heel. If only other areas of law besides copyright had loser-pays, and other states besides California emulated the “undertaking” idea. Earlier on Prenda Law here and here.
