  We show that the explanation of Thomas-Wigner rotation (TWR) and Thomas
precession (TP) in the framework of special theory of relativity (STR) contains
a number of points of inconsistency, in particular, with respect to physical
interpretation of the Einstein velocity composition law in successive
space-time transformations. In addition, we show that the common interpretation
of TP falls into conflict with the causality principle. In order to eliminate
such a conflict, we suggest considering the velocity parameter, entering into
expression for the frequency of TP, as being always related to a rotation-free
Lorentz transformation. Such an assumption (which actually resolves any causal
paradoxes with respect to TP), comes however to be in contradiction with the
spirit of STR. The results obtained are discussed.
