We investigate the possibility that the excess of four-jet events in e(+)e(-) collisions at LEP-1.5 which has been reported by the ALEPH Collaboration could be due to the production of charginos or neutralinos. followed by their decay into quark jets through baryon number-violating (lambda'') couplings. An estimate at the parton level shows, however, that these events cannot be due to neutralinos because of the low cross-section, and is unlikely to be due to the production of chargino pairs because of the largely different event shapes.
