Was the ruling for both Hernandez v. Texas and Berman v. Parker unanimous?
Hernandez v. Texas Hernandez v. Texas, 347 U.S. 475 (1954), was a landmark case, "the first and only Mexican-American civil-rights case heard and decided by the United States Supreme Court during the post-World War II period." In a unanimous ruling, the court held that Mexican Americans and all other nationality groups in the United States had equal protection under the 14th Amendment of the U.S. Constitution. The ruling was written by Justice Earl Warren. This was the first case in which Mexican-American lawyers had appeared before the US Supreme Court.
Puerto Rico v. Sanchez Valle Puerto Rico v. Sanchez Valle, 579 U.S. ___ (2016) , is a criminal case that came before the Supreme Court of the United States. In the case, the court considered whether Puerto Rico and the federal government of the United States are separate sovereigns for purposes of the Double Jeopardy Clause of the U.S. Constitution. In essence, this clause establishes that an individual cannot be tried for the same offense twice under the same sovereignty. The petitioner claimed that Puerto Rico possesses a different sovereignty because of the island's current political status while others claimed that it does not—including the respondent, the Supreme Court of Puerto Rico, and the Solicitor General of the United States. Finally, in a 6-2 decision, the court affirmed that the Double Jeopardy Clause bars Puerto Rico and the United States from successively prosecuting a single person for the same conduct under equivalent criminal laws.
