WASHINGTON - The US Supreme Court on Tuesday agreed to hear an appeal by former senior officials during George W. Bush's presidency seeking to block a lawsuit filed by immigrants, mainly Muslims, detained after the September 11 attacks who said they faced abusive treatment.

The former officials, including Attorney General John Ashcroft, FBI Director Robert Mueller and Immigration and Naturalization Services Commissioner James Ziglar, are aiming to reverse a 2015 ruling by the New York-based 2nd US Circuit Court of Appeals allowing the long-running suit to move forward.

Meanwhile, the apex court of the United States also agreed to decide whether people who have filed for bankruptcy can sue companies that attempted to collect old debt from them that was not required to be paid back because of state statutes of limitations.

The justices will hear an appeal filed by Midland Funding, a subsidiary of Encore Capital Group, which was sued by an Alabama debtor named Aleida Johnson, who entered bankruptcy in 2014. Midland sought payment of $1,879 in debt that Johnson had incurred more than a decade earlier. Alabama law sets a six-year statute of limitations for debt to be collected.
