WASHINGTON (AP) Chief Justice John Roberts is highlighting changes to federal court rules that he hopes will make lawsuits less expensive and time consuming.

Roberts says in the annual report he issues on the last day of the year that the rule changes that took effect a month ago are a "big deal" because they focus on ways to reduce delays and gamesmanship that plague civil lawsuits in the federal system.

Roberts has been on the Supreme Court since 2005.

Last year's report announced the Supreme Court's belated development of an electronic filing system similar to those used in courts around the country. Roberts offered no update on that work in the new report, but court officials have said they expect the system to come on line sometime in 2016.
