In the case of Sanabria v. United States, 1977, the Supreme Court ruled in favor of defendant Luis Sanabria by a vote of 6-3. The issue at hand was whether or not a single lottery could be considered multiple offenses under federal law due to each individual ticket sale being counted as an offense. The court held that Congress intended for each lottery scheme to constitute only one violation regardless of how many tickets were sold within it. Therefore, charging Mr. Sanabria with multiple counts based on individual ticket sales from one lottery operation violated his protection against double jeopardy (being tried twice for the same crime). This ruling clarified that when determining what constitutes an "offense" under federal gambling laws, courts should look at legislative intent rather than focusing solely on literal interpretation.

In the dissenting opinion for Sanabria v. United States, Justice Blackmun argued that the majority's interpretation of the statute was too narrow and failed to consider its broader implications. He believed that Congress intended to punish each separate illegal act as a distinct offense under this law. Therefore, he disagreed with the majority's view that only one violation could be charged per lottery operation regardless of how many bets were placed or tickets sold. In his view, each bet represented a separate violation because it involved an individual decision to participate in illegal gambling activity and thus contributed separately to societal harm caused by such activities. Furthermore, he contended that interpreting multiple violations from a single lottery operation would not lead to unfair punishment since penalties are determined based on factors like severity and frequency of offenses rather than mere number of charges.
