The right that is not afforded by the Sixth Amendment is The right to press charges in a countersuit against your accuser.
The Sixth Amendment of the U.S. Constitution provides various rights related to criminal prosecutions, such as the right to be informed of the charges, the right to a speedy and public trial by an impartial jury, and the right to have assistance of counsel (a lawyer) and to confront witnesses. However, the right to press charges in a countersuit is not included in the Sixth Amendment; that falls under civil law and is governed by different legal principles.
