The opinion is expressed, that well-known experiments on parity violation and CP-violation can be treated as signals of some new, yet unknown, level of matter. An hypothesis, which can be used as a base for some future model or theory is formulated. In the framework of this hypothesis, experiments which demonstrate parity violation or CP-violation do not contradict MRS or TRS conservation.6 pages, Latex, no figures, e-mail address after 10-May-96: taxt@cv.jinr.dubna.suHigh Energy Physics - Phenomenologytext
