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.

Opinion:
ARKANSAS v. MISSISSIPPI
No. 92,
Orig.
Final decree entered April 29, 1985
FINAL DECREE
The Report of the Special Master is received and ordered filed. The parties have presented a stipulation for entry of the proposed agreed decree. The Report of the Special Master is adopted and a final decree is entered accordingly.
It Is Ordered, Adjudged, and Decreed As Follows:
1. The common boundary between the States of Arkansas and Mississippi in the Mississippi River is the thalweg, which is the middle of the main navigable channel followed as the principal course of downstream navigation. This judgment determines the geographical location of this boundary in the reach of the Mississippi River, as more particularly described hereinafter, separating portions of Lee County, Arkansas and Tunica County, Mississippi in the vicinity of Bordeaux Point and Whiskey Island/Bordeaux Island.
2. Establishment of the common Arkansas-Mississippi boundary in “old” Walnut Bend, looping Whiskey Island/ Bordeaux Island, originated with the Bordeaux Chute Cutoff, which occurred in or about 1874 and was complete in or about 1883. The locus of that portion of the state boundary consisting of approximately the eastern one-half of “old” Walnut Bend has been subsequently established by long acquiescence by the States of Arkansas and Mississippi in private boundary lines resulting from prior litigation and agreements among the owners of lands adjacent thereto. The locus of these private boundaries, which the States of Arkansas and Mississippi have adopted by acquiescence as also being the locus of the interstate boundary, is as shown on the map of Mr. W. H. Guyer, a true and correct copy of which is attached hereto as Exhibit “A” and described by geodetic coordinates as Segment B, Points PA through PL, in the composite description set forth hereinafter. The remainder of the interstate boundary in approximately the western one-half of “old” Walnut Bend lies along the dead thalweg of the Mississippi River as it existed when the River’s flow ceased in this abandoned bendway subsequent to, and caused by, the Bordeaux Chute Cutoff. The locus of this portion of the interstate boundary in “old” Walnut Bend is as shown in Exhibit “B” and described as Segment B, Points Pm through Pbb in the composite description set forth hereinafter.
3. Establishment of the common Arkansas-Mississippi boundary along the southerly limit of Bordeaux Point originated with the Hardin Point Cutoff, constructed by the United States Army Corps of Engineers in 1942. In 1947, when the Mississippi River ceased to flow in this abandoned bendway (Fox Island Bend), the locus of the state boundary along the dead thalweg was determined by Mr. St. George Richardson, whose plat thereof has been accepted since that time by the States of Arkansas and Mississippi as correctly depicting this portion of the interstate boundary looping Bordeaux Point. A true and correct copy of the St. George Richardson survey is attached hereto as Exhibit “C” and described as Segment D in the composite description set forth hereinafter.
The common Arkansas-Mississippi boundary looping Bordeaux Point between Lee County, Arkansas and Tunica County, Mississippi, from the upper end of Mhoon Bend to the upper end of Fox Island Bend, exclusive of that portion of this boundary in “old” Walnut Bend looping Whiskey Island/Bordeaux Island, is depicted on Exhibit “D” and described as Segment A and Segments C and D in the composite description set forth hereinafter.
4. The common Arkansas-Mississippi state boundary looping Bordeaux Point between Lee County, Arkansas and Tu-nica County, Mississippi, from the upper end of Mhoon Bend to the upper end of Fox Island Bend, as depicted on Exhibits “B” and “D” hereto, is described using geodetic coordinates as follows:
