A Delaware Chancery Court judge has ruled in favor of eBay in a shareholder suit against Craigslist and majority shareholders Jim Buckmaster and Craig Newmark. The ruling rescinds a measure adopted by Craigslist's board that would have blocked a potential hostile takeover by San Jose, Calif.-based eBay.

The 2nd Circuit has refused to reconsider en banc its holding that antitrust laws are not violated when drug patent holders pay manufacturers of generic alternatives to keep competing products off the market.
