In suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise reexamined in any Court of the United States, than according to the rules of the common law.
Civil cases in which a settlement of more than $20 is being sued for, the trial by jury shall remain and that ruling in the court over that district of the civil criminal case unless overruled the Law of the Land.
This is just saying that any court case shall still remain so long as it has a viable amount due in the settlement. Once the ruling is given, it cannot be overturned.
This clip is from a show called Judge Judy, a T V court show showing the trial that which the 7th amendment gives right to in civil cases with a plaintiff and a defendant. These are small cases and fall under the civil city courts in the district in which the case happens. These kind of cases do not fall under State ruling or Supreme Court ruling.
Another case in which local courts rule over instead of the State courts. Malpractice lawsuits, although very high in settlement charges, are not state matters and as such fall under a speedy trial with judge and jury of peers. In most cases though, the judge is the one to make the over all decision in a civil matter ruling.
