Oracle has agreed to pay $46 million to settle claims that Sun Microsystems, which it acquired last year, submitted false claims to US agencies, the US Justice Department said on Monday.

The European Commission is studying the U.S. court decision favoring Oracle's PeopleSoft buyout and deciding whether to pursue its own objections.

Oracle is challenging the legality of PeopleSoft’s poison pill; trial on that case is scheduled to commence Sept. 27 in Delaware’s Court of Chancery.
