Several QSO pairs have been reported and their redshifts determined, where the two objects in each pair are located {\it across} an active galaxy. The usually accepted explanation of such occurrences is that the pair is ejected from the active galaxy. Currebtly interpreted redshifted spectra for both the QSOs imply that both the objects are receding from the observer. However, ejection can occur towards and away from the observer with equal probability. We argue that for a system with two QSOs {\it across} the parent galaxy, ejection should have occurred in opposite directions, whereby one object will be approaching us and the other will be receding from us. The former would be exhibiting a blueshifted spectrum. We analyse here a sample of four such pairs and show that the observed spectrum of one QSO in each pair can be interpreted as blueshifted. The other exhibits the ususal redshifted spectrum.A scenario based on the 'sling-shot' mechanism of ejection is presented to explain the ocurrences of the pairs in opposite sides of the active galaxies moving in opposite durections.
