Abstract: A lot of evidence has recently accumulated that physical characteristics of CP stars (delta m(1), Ca/Fe ratio, Li abundance, distribution of orbital periods, v sin i, Delta (V1-G), magnetic field) depend on orbital period or eccentricity. Consequently, the "tidal mixing + stabilization" hypothesis has been formulated to account for such features and the "binarity x magnetism" hypothesis of Abt & Snowden was reanalyzed. We conclude that all mentioned characteristics and properties of CP stars, including even CP star magnetism, may be affected or governed by binarity.
