 A majority of the Supreme Court on Wednesday appeared ready to strike down a key section of a law that withholds federal benefits from gay married couples, as the justices concluded two days of hearings that showed them to be as divided as the rest of the nation over same-sex marriage. 
 
 Justice Anthony M. Kennedy, the pivotal justice on the issue, said the federal Defense of Marriage Act (DOMA) may have intruded too deeply on the traditional role of state governments in defining marriage. The federal law recognizes marriages only between a man and a woman, and Kennedy said that ignores states “which have come to the conclusion that gay marriage is lawful.” 
 
 “Citizens’ day-to-day life” is affected by the more than 1,100 references to marriage contained in federal laws and regulations, Kennedy said, creating a “real risk of running in conflict with what has always been thought to be the essence of the state police power, which is to regulate marriage, divorce, custody.” 
 
 It appeared Kennedy’s interest in states’ rights might align with the concerns of the court’s four liberals that the law impermissibly targeted gay couples. Justice Ruth Bader Ginsburg said that the law, by withholding things such as tax advantages, Social Security benefits and leave to care for a spouse, raises a question: “What kind of marriage is it?” 
 
 A decision on DOMA — passed in 1996 when same-sex marriages were only theoretical — might be the most tangible development to come from the court’s two days of hearings on same-sex marriage. 
 
 On Tuesday, when considering an appeals court’s decision that overturned California’s voter-approved ban on same-sex marriage, the justices seemed to be looking for the narrowest way possible to resolve the case. They seemed reluctant to find that gay people have a constitutional right to marry. 
 
 In Wednesday’s nearly two hours of argument, the court also spent little time on another important legal issue the cases raised: whether laws affecting homosexuals deserved the kind of heightened scrutiny that courts use when examining possible discrimination against racial minorities. 
 
 But the arguments did reveal an unsurprising divide on the court, with liberal justices more supportive of gay rights and same-sex marriage and conservatives more tolerant of government action to protect “traditional marriage.” 
 
 At Wednesday’s arguments, Chief Justice John G. Roberts Jr. was skeptical of the idea that gay people might lack political power when it comes to government actions. 
 
 “You don’t doubt that the lobby supporting the enactment of same sex-marriage laws in different states is politically powerful, do you?” Roberts asked Roberta A. Kaplan, one of the lawyers bringing the challenge to DOMA. “As far as I can tell, political figures are falling over themselves to endorse your side of the case.” 
 
 “The fact of the matter is, Mr. Chief Justice,” Kaplan responded, “that no other group in recent history has been subjected to popular referenda to take away rights that have already been given or exclude those rights the way gay people have.” 
 
 Roberts was equally tough on the Obama administration. President Obama and Attorney General Eric H. Holder Jr. decided two years ago that DOMA was unconstitutional and have declined to defend the law in court. But the administration has continued to enforce it until the Supreme Court decides its fate. 
 
 If Obama has decided the law is unconstitutional, Roberts said, “I don’t see why he doesn’t have the courage of his convictions” to stop enforcing the law, “rather than saying, ‘Oh, we’ll wait till the Supreme Court tells us we have no choice.’ ” 
 
 The liberal justices sharply questioned former George W. Bush administration solicitor general Paul D. Clement, who is representing House Republican leaders who are defending DOMA. 
 
 He said the law, passed by overwhelming majorities in each chamber of Congress and signed by President Bill Clinton, was a reaction to the prospect that Hawaiian courts were on the verge of approving same-sex marriage. 
 
 Congress feared that “by the operation of one state’s state judiciary, same-sex marriage is basically going to be recognized throughout the country,” Clement said. “And what Congress says is: ‘Wait a minute. Let’s take a timeout here. This is a redefinition of an age-old institution.’ ” 
 
 Clement said Congress was within its powers to define marriage for the benefits it bestows and to strive for “uniformity” across the country by limiting those benefits to heterosexual couples. 
 
 He was strongly challenged by Justice Elena Kagan. She said that when Congress “targets a group that is not everybody’s favorite group in the world,” the court has an obligation to examine, “with some rigor, to say, ‘Do we really think that Congress was doing this for uniformity reasons or do we think that Congress’s judgment was infected by dislike, by fear, by animus and so forth?’ ” 
 
 She caused a stir in the courtroom, which appeared to be mostly filled with supporters of same-sex marriage, when she quoted language from a House committee’s analysis of the law: “Congress decided to reflect an honor of collective moral judgment and to express moral disapproval of homosexuality.” 
 
 Clement replied: “Does the House report say that? Of course, the House report says that.” But he added that the court has never struck a statute “just because a couple of legislators may have had an improper motive.” 
 
 Solicitor General Donald B. Verrilli Jr., representing the Obama administration, also sought to convince the court that the section of DOMA being challenged was motivated by prejudice. 
 
 When Roberts skeptically asked whether “the 84 senators who voted in favor of it and the president who signed it” were driven by animus, Verrilli said that was not the point. 
 
 The section, he said, “is discrimination.” 
 
 The case was brought by 83-year-old Edith Windsor, who watched from the second row. Windsor married Thea Spyer, her partner of more than 40 years, in Canada in 2007. Both were residents of New York. When Spyer died in 2009, she left her estate to Windsor. 
 
 At that time, the state of New York recognized the marriage. But because the marriage was not recognized by the U.S. government, Windsor paid a federal estate tax bill of more than $360,000 that would not have been assessed if she were married to a man. 
 
 The Obama administration agreed with the appeals court that ordered a refund but wanted the Supreme Court to render a definitive verdict on DOMA. 
 
 That led to the legal wrangling that dominated the first part of the argument and could lead to a decision that the case is not properly before the court. 
 
 A court-appointed lawyer, Harvard law professor Vicki C. Jackson, told the justices that Republican leaders in the House do not have proper standing to defend the law and that the Obama administration was not a viable party, because it agrees with the lower courts. 
 
 Roberts and Justice Antonin Scalia were the most critical of the approach the Obama administration has taken on the law. Roberts said the administration’s agreement with the lower court meant it was making an extraordinary request to have the Supreme Court consider it. 
 
 “You’re asking us to do something we’ve never done before,” Roberts said. 
 
 When Deputy Solicitor General Sri Srinivasan acknowledged that it was unusual, Roberts shot back: “No, not unusual — totally unprecedented.”

 WASHINGTON | 
 
 WASHINGTON (Reuters) - For the second day running, the Supreme Court convened on Wednesday to tackle the issue of gay marriage, this time to hear arguments over a law that denies federal benefits to legally married same-sex couples. 
 
 Almost two hours of oral argument will be heard by the court on the Defense of Marriage Act (DOMA). The nine justices heard arguments on Tuesday on the constitutionality of California's Proposition 8 ban on gay marriage. 
 
 In those arguments, the justices displayed a reluctance to rule broadly on the right to marry for gays and lesbians, suggesting the court may be similarly cautious about DOMA. 
 
 Rulings in both cases are expected by the end of June. 
 
 The cases come before the court as polls show growing support among Americans for gay marriage but division among the 50 states. Nine states recognize it; 30 states have constitutional amendments banning it and others are in-between. 
 
 DOMA limits the definition of marriage as between a man and a woman. It permits benefits such as Social Security survivor payments and federal tax deductions only for married, opposite-sex couples, not for legally married same-sex couples. 
 
 President Bill Clinton signed DOMA into law in 1996 after it passed Congress with only 81 of 535 lawmakers opposing it. Clinton, a Democrat, earlier this month said that times have changed since then and called for the law to be overturned. 
 
 The atmosphere outside the courthouse was more subdued than on Tuesday, when thousands of raucous protesters filled the sidewalks. A largely pro-gay marriage crowd of several hundred held signs and waved American flags. 
 
 Hundreds more waited patiently in line for a chance at the handful of seats in the courtroom allocated to the public. 
 
 "It was pretty cold," said Liz Ghandakhy, 28, a lawyer who got in line at 5:30 a.m. Tuesday and slept overnight on the sidewalk. "It's one of the greatest civil rights cases of our time." 
 
 A few minutes later, a beaming Ghandakhy was headed inside. 
 
 The DOMA case is about whether Edith Windsor, who was married to a woman, should get the federal estate tax deduction available to heterosexuals when their spouses pass away. 
 
 Windsor's marriage to Thea Spyer was recognized under New York law, but not under DOMA. When Spyer died in 2009, Windsor was forced to pay federal estate tax because the federal government would not recognize her marriage. She later sued the government, seeking a $363,000 tax refund. 
 
 Windsor's lawyers say the federal government has no role in defining marriage, which is traditionally left to the states. 
 
 Lower courts have ruled in her favor. 
 
 The roughly 133,000 gay couples nationwide, married in one of the nine states where it is legal, are not recognized as married by the federal government, Windsor's supporters say. 
 
 Various groups are calling for DOMA to be struck down, such as the Business Coalition for DOMA Repeal, whose members include Marriott International Inc, Aetna Inc, eBay Inc, and Thomson Reuters Corp, the corporate parent of the Reuters news agency. 
 
 OBAMA TURNS BACK ON DOMA 
 
 The Obama administration has agreed with Windsor that the section of law that defines marriage violates the U.S. Constitution's guarantee of equal protection under the law. The Justice Department has thus declined to defend the statute, as it normally would when a federal statute is challenged. 
 
 That has left a legal group acting on behalf of the Republican-dominated U.S. House of Representatives, known as the Bipartisan Legal Advisory Group, or BLAG, as the party defending the federal law. Its lawyer, Paul Clement, will argue that there are several reasons to support Congress's decision to enact DOMA. 
 
 Noting the strong bipartisan support the law attracted when enacted, Clement said in court papers that a move to strike it down as unconstitutional "would be wholly unprecedented." 
 
 Before the court reaches that bigger question, preliminary matters could prevent a decision. One is whether BLAG has legal standing. If such a procedural issue prevents the court from deciding the case on the merits, Windsor would win her refund. 
 
 Yet DOMA would stay on the books in states where courts have not ruled on it. Further litigation would likely ensue.

– The Supreme Court heard arguments on California's Prop 8 yesterday; today, the federal Defense of Marriage Act is on the docket. What to expect: What is today's case about? DOMA defines marriage as a union between one man and one woman, meaning that gay couples who legally wed in states that allow gay marriage are denied federal benefits. The high court must decide if the federal government can constitutionally do that. The specific case being considered involves Edith Windsor, 83, who married partner Thea Spyer in 2007. When Spyer died, Windsor was hit with a $363,000 estate tax bill because their marriage wasn't recognized. She's suing for a refund. Will Windsor be there? She is expected to be, but her health is declining, USA Today reports. How many people are affected? There are about 133,000 married gay couples not currently recognized by the feds, Reuters reports. The Washington Post points out that while yesterday's case involved people not yet married, today's involves people who are. What are the tax implications? If the Supreme Court strikes down DOMA, taxes for some same-sex couples might actually go up, Politico reports. The so-called "marriage penalty" means that when couples whose incomes are similar file a joint tax return, they don't get as many tax breaks as they would have had they filed separately. That "penalty" could end up applying to gay couples who currently skirt it. How will yesterday's session affect today's? It may not. Yesterday's case could potentially involve a much broader ruling; the court could theoretically strike down Prop 8 and also extend gay marriage rights to all states. But the justices seemed wary of doing that. So, Reuters notes, that case may have little bearing on today's, since DOMA is a much narrower question. And, as NPR reports, it's also "a much clearer question," and the themes that come up today aren't likely to be similar to yesterday's. The only two expected outcomes: Is DOMA constitutional or not? When is a decision expected? Late June. A ruling on the Prop 8 case is expected at the same time. Is there a possibility there won't be a decision? Yes. The Obama administration refuses to defend DOMA in court, so House Republican leaders are defending it. The court could decide that those members have not suffered an injury that would allow them to bring the case, and could thus decide not to rule on it.
