二 |     WASHINGTON -- The Supreme Court on Monday ordered two internet sellers of gun parts to comply with a Biden administration regulation aimed at ghost guns, firearms that are difficult to trace because they lack serial numbers.The court had intervened once before, by a 5-4 vote in August, to keep the regulation in effect after it had been invalidated by a lower court. No justice dissented publicly from Monday's order, which followed a ruling from a federal judge in Texas that exempted the two companies, Blackhawk Manufacturing Group and Defense Distributed, from having to abide by the regulation of ghost gun kits.Other makers of gun parts also had been seeking similar court orders, the administration told the Supreme Court in a filing.“Absent relief from this Court, therefore, untraceable ghost guns will remain widely available to anyone with a computer and a credit card — no background check required,” Solicitor General Elizabeth Prelogar, the administration's top Supreme Court lawyer, wrote. The regulation changed the definition of a firearm under federal law to include unfinished parts, like the frame of a handgun or the receiver of a long gun, so they can be tracked more easily. Those parts must be licensed and include serial numbers. Manufacturers must also run background checks before a sale — as they do with other commercially made firearms. The requirement applies regardless of how the firearm was made, meaning it includes ghost guns made from individual parts or kits or by 3D printers.The regulation will be in effect while the administration appeals the judge's ruling to the 5th U.S. Circuit Court of Appeals in New Orleans — and potentially the Supreme Court.。而现在，香港的新车销量似乎发生了一些变化，日系品牌正逐渐淡出榜单，是哪些品牌替代了日系的位置？你我可能都没想到。● 香港人为什么钟爱日系车？为什么喜欢MPV？年轻人对买车缺乏热情？香港，作为一个高度发达的城市，经济地位在亚洲首屈一指。能代表经济实力的人均GDP显示，2024年香港特别行政区人均GDP为53165美元（约合人民币38.2万元），而北京是32019美元（约合人民币23万元）。
