Joe Luna, Appellant v. the State of Texas, Appellee

Summary

The Court affirmed the conviction for heroin sale, holding that the second prosecution did not violate double jeopardy because the sales were separate acts, that the 74‑day indictment delay did not breach the speedy trial guarantee, that there is no constitutional right to probation, and that the chain of custody for the heroin packets was sufficient. The decision relied on Texas and United States precedent and rejected all of appellant's asserted errors.
