Boykin Tahl Waiver
When a defendant enters into a “guilty” or “no contest” plea he or she must make a knowing and voluntary waiver of the right to a jury trial, the right to confront witnesses and the right against self-incrimination, otherwise the plea is not valid and unconstitutional. A waiver of these three rights is known as a Boykin-Tahl waiver.
