No. Judges cannot overturn when you have been found not liable.
It is called the verdict. In a criminal case it will be Guilty or Not Guilty. In a civil case it will be Liable or Not Liable.
There probably aren't statistics for the whole country, but a judgment not withstanding, such an occurrence is rare.
I am going to assume this has to deal with criminal law as it is in the "Crime and Criminal Law", so this information does not apply to civil (Though it is similar). The good news is that if a jury returns a verdict of not guilty, that is it - the defendant is not guilty on those charges. It can never be overturned (Assuming there is not some type of jury problem and there is a retrial). Basically, an appeals court can never overturn a not guilty verdict when it is returned by a jury. This is based on the doctrine of claim preclusion. If someone could be tried twice on the same charges, this would be a deprivation of the 14th amendment due process right afforded to the defendant by the state. There are some instances to take note of, however. One being when the jury returns a guilty verdict, and the judge grants a motion notwithstanding the verdict (Essentially overturning the jury's verdict and finding the defendant not guilty). This CAN be appealed and overturned. This is not subject to claim preclusion. Good luck.
Loudly.
a Not-Guilty verdict

No. Civil is majority must agree.
The laws that govern appeals in Washington are the Rules of Appellant Proceedure. To go through them all here is not possible - although you may refer to your local library for a copy of WA state laws, or utilize a search engine.
It depends on the state
The jury can give two verdicts, guilty, or not guilty in a criminal trial. They are typically given a set of charges that they have to give a verdict on. Some allow them to convict on a lessor included charge. Meaning if someone is charged with first degree murder, they could convict of second degree murder. If the jury cannot decide on a verdict, it can be ruled a hung jury. At that point the trial can start all over again with a new jury. In a civil trial, the jury determine if they are liable or not liable.
The question is unclear. The Court of Appeals has equal authority to review both civil and criminal cases appealed to it for review.
