High-spin states in $^{142}Gd$ have been populated by means of the $^99{Ru}$($^48{Ti}$,2p3n) reaction at 240 MeV and investigated with the $\gamma$-spectrometer EUROBALL III and the charged-particle detector array ISIS. The features of four dipole bands have been determined and compared with tilted-axis cranking model calculations indicating that they are magnetic rotational bands. A transition from regular to irregular bands has been found approaching $N = 82$ demonstrating that this is a general phenomenon in nuclei near a double-shell closure
