What follows is an opinion from the Supreme Court of the United States. Your task is to identify the petitioner of the case. The petitioner is the party who petitioned the Supreme Court to review the case. This party is variously known as the petitioner or the appellant. Characterize the petitioner as the Court's opinion identifies them.

Identify the petitioner by the label given to the party in the opinion or judgment of the Court except where the Reports title a party as the "United States" or as a named state. Textual identification of parties is typically provided prior to Part I of the Court's opinion. The official syllabus, the summary that appears on the title page of the case, may be consulted as well. In describing the parties, the Court employs terminology that places them in the context of the specific lawsuit in which they are involved. For example, "employer" rather than "business" in a suit by an employee; as a "minority," "female," or "minority female" employee rather than "employee" in a suit alleging discrimination by an employer.

Also note that the Court's characterization of the parties applies whether the petitioner is actually single entity or whether many other persons or legal entities have associated themselves with the lawsuit. That is, the presence of the phrase, et al., following the name of a party does not preclude the Court from characterizing that party as though it were a single entity. Thus, identify a single petitioner, regardless of how many legal entities were actually involved. If a state (or one of its subdivisions) is a party, note only that a state is a party, not the state's name.

1. That the extension of the boundary southerly from the point where the line forming the boundary between Texas and Louisiana southerly from the Arkansas boundary, intersects the geographical middle of the Sabine River (Latitude 31°59' 56.225" North, Longitude 94°02/33.105" West, said point being taken from the United States Geological Survey Quadrangle Center, Tex.-La. 1958 Edition) to the mid-point between the gulfward extension of the Sabine Pass jetties Latitude 29°38'37.329" North, Longitude 93°49/30.940" West hereby is established.
Said boundary commences at Latitude 31°59/56.225" North and Longitude 94°02/33.105" West, thence proceeding in a southerly direction along the Sabine River using the federal line as shown for the boundary on the United States Geological Survey Quadrangle Center, Tex.-La., 1958 Edition (photo-revised 1969) and signed by Hatley N.

2. That the offshore lateral boundary between the States of Texas and Louisiana seaward from the point Latitude 29° 38' 37.329" North, Longitude 93°49'30.940" West (end of jetties) is a line running South-Southeasterly from said point on a constant bearing of South 13°44'45.8" east true to the seaward limit of Louisiana’s Submerged Lands Act grant. Texas’ historic boundary then continues offshore on the same bearing to the point Latitude 29°32'06.784" North, Longitude 93°47' 41.699" West. This offshore lateral boundary and the Texas historical boundary are shown upon Exhibit 14 which is in evidence in this case.
3.

Louisiana does not hold title to or interest in any island in the west half of the Sabine River. The United States and Texas do not hold title to or interest in any island in the east half of the Sabine River.
4. That Exhibits 1-14, in evidence herein and above mentioned, be certified by the Special Master as delineating the boundary between the State of Texas and the State of Louisiana, from Latitude 32° North, as defined herein, to the seaward limits of Louisiana’s Submerged Land Act grant, and the seaward limits of Texas’ historical boundary, as defined herein, and that the State of Louisiana be directed to deposit a copy of these maps, so certified by the Special Master, along with a certified copy of this decree, with the Register of -the State Land Office for the State of Louisiana, and that the State of Texas be directed to deposit a set of these maps, so certified by the Special Master, along with a certified copy of this decree, with the Commissioner of the General Land Office of the State of Texas.
5. That the costs be taxed to the parties in accordance with their contribution to the fund established by the Special Master, and that no costs be taxed for the services of the Special Master.
6. That any unexpended funds contributed by the parties to the Special Master for necessary expenses be returned to the parties.
7. That upon such return of funds the Honorable Robert Van Pelt, the Special Master appointed in this cause, will have completed his duties, and is thereupon discharged.
