no. jury nullification is not supported by the common law. nor does it derive from the magna carta, the dongan patent or any other old english laws or proclamations.
The power of the jury to judge the justice of the law and to hold laws invalid by a finding of "not guilty" for any law a juror felt was unjust or oppressive, dates back to the Magna Carta, in 1215. At the time of the Magna Carta, King John could pass any law any time he pleased. Judges and executive officers, appointed and removed at his whim, were little more than servants of the King. The oppression became so great that the nation rose up against the ruler, and the barons of England compelled their king to pledge that he would not punish a freeman for a violation of the law without the consent of his peers.

as for the constitution being a legal syllabus, who are you? who is some juror to decide what is constitutional and put themselves before the courts, while lying to the court to take such a stand?
I didn't say the Constitution is a legal syllabus. I said it isn't.
As to who I am, I am one among many who disagree with your authoritarian/submissive view of the world and agree with the following legitimate experts on the subject:
Several state constitutions, including the Georgia Constitution of 1777 and the Pennsylvania Constitution of 1790 specifically provided that "the jury shall be judges of law, as well as fact." In Pennsylvania, Supreme Court Justice James Wilson noted, in his Philadelphia law lectures of 1790, that when "a difference in sentiment takes place between the judges and jury, with regard to a point of law,...The jury must do their duty, and their whole duty; They must decide the law as well as the fact." In 1879, the Pennsylvania Supreme Court noted that "the power of the jury to be judge of the law in criminal cases is one of the most valuable securities guaranteed by the Bill of Rights."
John Jay, the first Chief Justice of the U. S. Supreme Court stated in 1789: "The jury has the right to judge both the law as well as the fact in controversy." Samuel Chase, U. S. Supreme Court Justice and signer of the Declaration of Independence, said in 1796: "The jury has the right to determine both the law and the facts. " U. S. Supreme Court Justice Oliver Wendell Holmes said in 1902: "The jury has the power to bring a verdict in the teeth of both law and fact." Harlan F. Stone, the 12th Chief Justice of the U. S. Supreme Court, stated in 1941: "The law itself is on trial quite as much as the cause which is to be decided."
In a 1952 decision (Morissette v United States), the U. S. Supreme Court recognized the powers of juries to engage in nullification. The court stated:
"Had the jury convicted on proper instructions it would be the end of the matter. But juries are not bound by what seems inescapable logic to judges....They might have refused to brand Morissette as a thief. Had they done so, that too would have been the end of the matter."
In a 1972 decision (U. S. v Dougherty, 473 F 2nd 1113, 1139), the Court said: "The pages of history shine on instances of the jury's exercise of its prerogative to disregard instructions of the judge."
So any court that seeks to constrain me from exercising what clearly is my right to follow the dictate of my conscience deserves to be lied to. If you believe the constraints placed on jurors by the regulations imposed for the purpose of leading a jury down a narrowly restrictive path it logically follows that there really is no need for juries. We might as well accept that a judge should simply refer to the "facts" and issue the verdict himself. Because as an endowed legal expert he certainly must be more capable of doing so than are a dozen lesser humans.
