The Oregon case vs. Mitchell dates back to 1970 and appeared at the United States Federal Supreme Court. In that case, the state of Oregon called on the Supreme Court to declare a law unconstitutional that forces states to register its residents between the ages of 18 and 21 as voting rights. In some states, including Oregon, the official voting age was 21.
The court was partly in agreement with Oregon; The judges decided that Congress could not establish a minimum age for voting for state elections, but for presidential elections. The sentence was not implemented immediately because the states of 21 should keep track of two electoral registers. The court decision was rejected when the 26th amendment was adopted the following year, which allowed the minimum age to vote federally as 18 years.
John Mitchell, whose name was named, was the Minister of Justice at the time of the trial.
