A federal judge wants an aggressive schedule for the Marriott data breach lawsuits, telling lawyers Thursday that he planned to rule on motions to dismiss the cases by the end of the year.

The judge outlined his scheduling plans at a hearing as Marriott International Inc. prepares to file motions to dismiss the cases, brought by consumers, financial institutions, shareholders and the city of Chicago, which filed its own case Feb. 14. U.S. District Judge Paul Grimm of the District of Maryland, who is overseeing almost 100 class actions brought over last year’s breach, said he did not want the litigation bogged down.
