    "abstract": "We argue that most of the relativistic 3-D (quasipotential) equations used in\nhadron physics are inconsistent with the discrete symmetries like charge\nconjugation and CPT, yielding an incorrect Lorentz structure for the calculated\nGreen\u0027s functions. An exception to this is the equal time approximation to the\nBethe-Salpeter equation. We present a covariant quasipotential model for the\npion-nucleon interaction based on hadronic degrees of freedom and satisfying\nthe full covariance.",
