Behind the pendulum-like regulatory swings between interventionism and laissez-passer that are nothing but the results of changing contexts are the legal principles as their denominators and connectors. Legal principles guide explanations and give paths that a decision maker must not circumvent. In the enhanced dynamic environment that is based more on risk and prediction than solely ex post adaptation they cannot cope with the more numerous information and communication channels. Principles can be more fully embraced with the help of more systematically-elaborated reality. Without clear steps needed for the formation of principles talks about the regulatory impact assessment, risk management, evidence-based approach and other regulatory notions are only a stuff for filling the paper lines than the real tools for the management of reality.
