  A nonstationary anomalous Hall current is calculated for a voltage biased
Josephson junction, which is composed of two s-wave superconducting contacts
deposited on the top of a three dimensional topological insulator (TI). A
homogeneous Zeeman field was assumed at the surface of TI. The problem has been
considered within the ballistic approximation and on the assumption that
tunneling of electrons between contacts and the surface of TI is weak. In this
regime the Josephson current has no features of the $4\pi$-periodic topological
effect which is associated with Andreev bound states. It is shown that the Hall
current oscillates in time. The phase of these oscillations is shifted by
$\pi/2$ with respect to the Josephson current and their amplitude linearly
decreases with the electric potential difference between contacts. It is also
shown that the Hall current cannot be induced by a stationary phase difference
of contact's order parameters.
