PROVIDENCE, R.I. (AP) — Lawyers for a Texas natural gas company convicted of illegally storing mercury in Rhode Island have told a judge he should limit the company’s fine to no more than $50,000 after the U.S. Supreme Court struck down the original $18 million penalty.

In the same hearing Monday, U.S. District Court Judge William Smith wondered aloud whether he could instead require “higher-ups” in the Southern Union Co. to perform community service as a condition of the sentence.
