The Delaware Supreme Court ruled in favor of Chicago Bridge & Iron Co on Tuesday in its in $2 billion dispute with Westinghouse Electric Co that stems from cost overruns at a pair of unfinished U.S. nuclear power plants. The two companies have been sparring over a 2015 deal in which Westinghouse, a unit of Japan's Toshiba Corp <6502.T>, bought the Shaw nuclear construction business of Chicago Bridge. Westinghouse later sought an adjustment to the closing deal price, sparking a dispute over accounting.

Negotiations over increasing Illinois' payments to Medicaid providers have failed, opening the door for a U.S. judge to force the cash-strapped state to pay as much as $1 billion a month to ensure medical care continues for the program's three million recipients, according to a court filing on Monday. It could force Illinois to stop making full payments on other state-mandated or court-ordered spending such as pensions and payroll. The filing in U.S. District Court by attorneys representing Medicaid recipients asked Judge Joan Lefkow to order the state to pay $500 million a month for four months to start reducing a $3.1 billion pile of unpaid bills owed to managed care organizations that turn pay doctors and others.

Yale University has sued the state of Connecticut over rules it says limit the number of gender-neutral bathrooms it can designate on campus, the latest skirmish in the broader U.S. fight about gender identity. The Ivy League school said in the lawsuit it wants to designate all single-occupant restrooms at its law school as gender neutral, but the plan would run afoul of the state building code, which does not count gender-neutral bathrooms when it assesses whether a public building has enough toilets. The suit was filed on Friday in Connecticut Superior Court in New Haven, after the university received complaints from law school students.

The U.S. Supreme Court on Tuesday threw out a lower court ruling prohibiting the use of public funds to pay for children to attend private religious schools, a day after it issued a major ruling narrowing the separation of church and state. The justices ordered the lower court in Colorado to reconsider the legality of school "voucher" programs in light of Monday's ruling that churches and other religious entities cannot be categorically denied public money even in states whose constitutions explicitly ban such funding. In that case, the justices sided with a Missouri church that objected when the state denied it access to public funds for a playground improvement project.

The U.S. Supreme Court on Tuesday agreed to decide whether people injured in a 1997 bombing attack in Jerusalem can seek to enforce a $71 million judgment against Iran over its alleged role by seizing ancient Persian artifacts held by two Chicago museums. The justices will hear the plaintiffs' appeal of a ruling last year in favor of Iran by the Chicago-based 7th U.S. Circuit Court of Appeals. The court's ruling in the case is also likely to dictate the outcome of a similar dispute pending before the justices in which four different groups of plaintiffs representing those injured in other allegedly Iran-backed attacks are seeking to enforcement court judgments by seizing $17.6 million in assets held by Iranian government-owned Bank Melli.

By Steve Friess DETROIT (Reuters) - A federal judge halted late on Monday the deportation of all Iraqi nationals detained during immigration sweeps across the United States this month until at least July 10, expanding a stay he imposed last week. The stay had initially only protected 114 detainees from the Detroit area. U.S. District Judge Mark Goldsmith sided with lawyers from the American Civil Liberties Union who filed an amended complaint on Saturday seeking to prevent Immigration and Customs Enforcement (ICE) from deporting Iraqis from anywhere in the United States.
