Query: Comments on ''The Principle of Self-Consistency as a consequence of the
  Principle of Minimal Action''   The so called ''Principle of the self-consistency'' for space-time models
with causality violation, which was firstly formulated by I.D.Novikov, is
discussed for the test particle motion and for test scalar field. It is shown
that the constraints, which provide the self-concistensy of test particle
motion have pure geometrical (topological) nature. So, the recent statement
that ''The Principle of self-consistensy is a consiquence of the Principle of
minimal action'' is wrong.
