The Supreme Court on Tuesday turned away three appeals from military contractor KBR Inc. that seek to shut down lawsuits over a soldier's electrocution in Iraq and open-air burn pits in Iraq and Afghanistan.

The justices offered no comment in allowing the lawsuits to proceed.

One lawsuit was filed by the parents of Staff Sgt. Ryan Maseth, who was electrocuted in his barracks shower at an Army base in Iraq in 2008. The suit claims KBR unit Kellogg Brown & Root Services Inc. was legally responsible for the shoddy electrical work that was common in Iraqi-built structures taken over by the U.S. military. KBR disputes that claim.

Dozens of lawsuits by soldiers and others assert they were harmed by improper waste disposal while serving in Iraq and Afghanistan. They seek to hold KBR and Halliburton Co. responsible for exposing soldiers to toxic emissions and contaminated water when they burned waste in open pits without proper safety controls.

The contractors say they cannot be sued because they essentially were operating in war zones as an extension of the military.

The Obama administration agreed with the contractors that lower courts should have dismissed the lawsuits, but said the Supreme Court should not get involved now because lower courts still could dismiss or narrow the claims.

The Supreme Court won't hear a challenge to part of Vermont's campaign finance laws that impose contribution limits on political action committees.

The justices on Monday declined to hear an appeal from the Vermont Right to Life Committee, an anti-abortion group. The group argued that Vermont's campaign finance registration, reporting and disclosure requirements for PACs were too broad and unconstitutional.

The group argued that a subcommittee it created should not be subject to Vermont's $2,000 limit on contributions to PACs because the subcommittee does not give money directly to candidates and makes only independent expenditures.

But a federal judge rejected those arguments, finding that there was no clear accounting between the two committees. A federal appeals court agreed.

A New Delhi court charged an Uber cab driver on Tuesday with rape, kidnapping and criminal intimidation in a case that has renewed a national fury over chronic sexual violence in India. Authorities are still investigating whether Uber should also be charged.

Judge Kaveri Baweja ordered the case to begin Thursday in a special fast-track court set up in 2013 to bypass India's lumbering judicial system.

The 32-year-old suspect, Shiv Kumar Yadav, entered a plea of innocence. He has been in custody since a 25-year-old woman filed a police complaint alleging he assaulted her after she hired him for a ride home on Dec. 5.

Authorities, meanwhile, were still investigating the possibility of criminal charges against the company for allegedly misrepresenting the safety of its service, police official Brijendra Kumar Yadav said.

"That is a separate case, and will take some time," he said, without giving details.

The case has appalled many in India, occurring almost exactly two years after a young woman was fatally gang raped on a bus in the capital. It has sparked new demands for better protections for women.

It also dealt a blow to Uber, which has attracted global praise and controversy with a service that lets passengers summon cars through an app in more than 250 cities around the world.

The highest court in Massachusetts is hearing arguments in a case that could determine the fate of thousands of people convicted of drug crimes based on tainted evidence.

The American Civil Liberties Union says many of those affected are afraid to vacate their guilty plea and seek a new trial because they can be prosecuted for crimes dropped when they entered their plea deal.

The ACLU will argue Thursday morning that the Massachusetts Supreme Judicial Court should declare that any defendant who seeks a new trial cannot be convicted of a more serious offense or given a longer sentence.

The case comes after former state drug lab chemist Annie Dookhan admitted she faked test results and tampered with evidence.

Dookhan was sentenced to at least three years in prison in 2013.

The Republican-led Congress appears ready to approve the Keystone XL oil pipeline, but no matter what actions are taken in Washington, the entire 1,179-mile project could be delayed until Nebraska signs off on the route.

After several years of intense debate, the routing process is before the Nebraska Supreme Court, and depending on how the justices rule, months or years could pass before construction begins in that state.

Even if approval comes from Washington and the high court, opponents are looking for new ways to block the project, including filing a federal lawsuit on behalf of Native American tribes in Nebraska and South Dakota over the possible disruption of Indian artifacts.

The court is considering whether an obscure agency known as the Nebraska Public Service Commission must review the pipeline before it can cross the state, one of six on the pipeline's route. Gov. Dave Heineman gave the green light in 2013 without the involvement of the panel, which normally regulates telephones, taxis and grain bins.

The justices have given no indication when they will render a decision.

President Barack Obama has said he is waiting for the court's decision, and the White House on Tuesday threatened to veto the bill in what was expected to be the first of many confrontations with the new Congress over energy and environmental policy.

Argentina's Supreme Court has ruled that an American who took refuge and started a new life in the South American country can be extradited to face charges that he killed his wife over a decade ago, a court spokeswoman confirmed Saturday.

Kurt Sonnenfeld moved to Argentina in 2003 and sought asylum after prosecutors in Denver charged him with first-degree murder. The decision to extradite him brings to an end a longstanding dispute between the U.S. Justice Department and Argentine courts that centered in part on differences over the death penalty.

In the ruling, which was made Dec. 11, the justices said U.S. prosecutors had assured Argentina that "the death penalty will not be imposed, or if it were ruled, it will not be exercised in this case." The ruling said the executive branch will have final say on an extradition and doesn't specify when it may take place.

Maria Bourdin, a spokeswoman for Argentina's Supreme Court, confirmed the ruling but declined to comment beyond what was in it. Calls to the U.S. Embassy in Buenos Aires on Saturday seeking comment were not immediately returned.
