7. Myrna leased her real property to Geybin for a period of one year. However, Geybin refused to vacate the premises after the expiration of the lease. Myrna then filed against Geybin an unlawful detainer case. The Metropolitan Trial Court (MeTC) ruled in favor of Myrna and ordered Geybin to surrender the real property. The judgment of the MeTC lapsed into finality but was not enforced. For humanitarian reasons, Myrna allowed Geybin to stay on the real property provided he will surrender its possession when needed. Thereafter, Myrna demanded from Geybin to vacate the premises but was refused. Myrna filed against Geybin another unlawful detainer case. In his answer, Geybin argued that the second ejectment case is barred by the prior final judgment in the first ejectment case. Does res judicata bar the institution of the second unlawful detainer case? Explain.
