Silvesterpatent: law signed by Emperor Franz Joseph I on December 31, 1851, which repealed basic rights and the constitution of March 4, 1849, which had never entered into force. What remained was the principle of equality of all citizens before the law, and the abolition of economic servitude. The Silvesterpatent formed the basis of Neo-absolutism. The so called "principles" (which regulated administrative and judicial services and were published at about the same time), were also valid for Hungary and the territories under Hungarian control. The Silvesterpatent was drawn up by K. F. v. Kuebeck, and initiated by A. v. Bach.
