Prison sucks, and any prison sentence can feel like cruel and unusual punishment in Texas. Can a sentence be too long to be constitutional? Theoretically yes, the Constitution places limits on how long someone can be sentenced, but in practice, it’s an argument that our appellate courts routinely reject.
How can a prison sentence be unconstitutional?
The 8th amendment forbids cruel and unusual punishment. Over the years the Supreme Court has indicated that a sentence could be so long that it is disproportionate to the crime committed, and therefore unconstitutional. However, our Texas Court of Criminal Appeals (kind of a Supreme Court for criminal cases in Texas) is run by former prosecutors who don’t mind how long people rot in prison.
