Ethics

There's a fine line between hard litigation (ok) and harassing litigation (not ok), and courts have been scrutinizing the tactic of taking the deposition of the opposing party's CEO when, arguably, the CEO has no relevant knowledge.  Point of Law has details and links to recent cases.

While you're at Point of Law, you might read this post about the economics of plaintiffs-side work. The post discusses tax treatment of expenses for trial lawyers -- which don't strike me as sinister -- and provides a nice insight into funding of plaintiffs' cases.
