Abstract. For the equation

\begin{displaymath}Lz=K(y)z_{xx} +z_{yy} =0,\end{displaymath}

where $yK(y)>0$ for $y\ne 0$) in $D$, bounded by a Jordan (non-selfintersecting) "elliptic" arc $\Gamma $ (for ó $>$ 0) with endpoints $A(0,0)$and $B(l,0),\; l>0$, and for $y<0$ by a characteristic $\gamma _{1} $ through A which meets the characteristic $\gamma _{2} $ through B at the points C, the uniqueness of the Morawetz problem is proved without assuming that $\Gamma $ is monotone.
