What it's about

The Supreme Court ruled that the Sixth Amendment’s protection does not cover delays after a guilty plea or guilty verdict and agreed with Montana’s court (affirmed); it did not decide whether the delay violated due process.

Betterman’s appeal raised only the Sixth Amendment issue; a due-process challenge was not before the Court.

Question presented

Is it a violation of the Sixth Amendment right to a speedy trial to postpone sentencing for fourteen months after a guilty plea has been issued?

What the Court decided

Holding

The Sixth Amendment’s speedy trial guarantee does not apply once a defendant has been found guilty at trial or has pleaded guilty to criminal charges. 378 Mont. 182, 342 P. 3d 971, affirmed.
