<P0-S0>  Over time, federal statutes and Supreme Court rulings have designated more or less power to tribal governments, depending on federal policy toward Indians. <P0-S1> Indian country jurisdiction, or the extent which tribal powers apply to legal situations in the United States, has undergone many drastic shifts since the beginning of European settlement in America. <P0-S2>  Numerous Supreme Court decisions have created important precedents in Indian country jurisdiction, such as "Worcester v. Georgia", "Oliphant v. Suquamish Tribe", and "Montana v. United States". <SEP> <P1-S0> Worcester v. Georgia, 31 U.S. (6 Pet.) <P1-S1>  515 (1832), was a case in which the United States Supreme Court vacated the conviction of Samuel Worcester and held that the Georgia criminal statute that prohibited non-Native Americans from being present on Native American lands without a license from the state was unconstitutional. <SEP> <P2-S0> The Taney Court refers to the Supreme Court of the United States from 1836 to 1864, when Roger Taney served as the fifth Chief Justice of the United States. <P2-S1>  Taney succeeded John Marshall as Chief Justice after Marshall's death in 1835. <P2-S2>  Taney served as Chief Justice until his death in 1864, at which point Salmon P. Chase took office. <P2-S3>  Taney had been an important member of Andrew Jackson's administration, an advocate of Jacksonian democracy, and had played a major role in the Bank War, during which Taney wrote a memo questioning the Supreme Court's power of judicial review. <P2-S4>  However, the Taney Court did not strongly break from the decisions and precedents of the Marshall Court, as it continued to uphold a strong federal government with an independent judiciary. <P2-S5>  Most of the Taney Court's holdings are overshadowed by the "Dred Scott" decision, in which the court ruled that African-Americans could not be citizens. However, the Taney Court's decisions regarding economic issues and separation of powers set important precedents, and the Taney Court has been lauded for its ability to adapt regulatory law to a country undergoing remarkable technological and economic progress. <SEP> <P3-S0> Jeffrey Keith "Jeff" Skilling (born November 25, 1953) is the former CEO of Enron Corporation. <P3-S1>  In 2006, he was convicted of federal felony charges relating to Enron's collapse and is currently serving 14 years of a 24-year, four-month prison sentence at the Federal Prison Camp (FPC) – Montgomery in Montgomery, Alabama. <P3-S2>  The Supreme Court of the United States heard arguments in the appeal of the case March 1, 2010. <P3-S3>  On June 24, 2010, the Supreme Court vacated part of Skilling's conviction and transferred the case back to the lower court for resentencing. <P3-S4>  During April 2011, a three-judge 5th Circuit Court of Appeals panel ruled that the verdict would have been the same despite the legal issues being discussed, and Skilling's conviction was confirmed; however, the court ruled Skilling should be resentenced. <P3-S5>  Skilling appealed this new decision to the Supreme Court, but the appeal was denied. <P3-S6>  In 2013, the United States Department of Justice reached a deal with Skilling, which resulted in ten years being cut from his sentence.
