Rule of law are some groups of laws, institutionas and community commitment that support the equality of all citizens before the law, prevent the government from being arbitrary as well as the use of power in an arbitrary form. By avoiding arbitrariness we mean that it doesn't give a special treatment to anyone or anything, following the procedures in an standarized manner.
Under the rule of law both government and private actors are accountable under the law, the laws are public and clear and the process is open. In other words "no one is above the law".
