What is the basis for the seventh amendment right to a civil trial by jury? Is it the Magna Carta, the English common law or the preamble to the constitution or the bill of rights?

The basis for the Seventh Amendment right to a civil trial by jury is the English common law. The Seventh Amendment of the United States Constitution guarantees the right to a jury trial in civil cases where the value in controversy exceeds $20. It is important to note that the Magna Carta and the English common law played significant roles in shaping the legal systems of the United States, including the right to trial by jury. However, the specific basis for the Seventh Amendment can be traced back to the English common law tradition. The Preamble to the Constitution and the Bill of Rights establish broader principles and rights, but do not directly address the right to a civil trial by jury.
