It is not unusual in Bb. Pilipinas to have the top titleholder dethroned with another winner lesser in rank taking over her place. 1991 must have been one of the earlier years that set the stronger precedent when Anjanette Abayari was replaced (due to citizenship issues if memory serves me right) by Miss Maja Pilipinas Alou Gonzales who went on to represent us in Miss Universe won by Lupita Jones and which had singer Kuh Ledesma as one of the judges. I say stronger precedent because back in 1984, Miss Maja Pilipinas Bella Nachor represented us in Miss International when 24 year-old Catherine Jane Brummitt was turned down by the Japanese organizers due to age disqualification.
At any rate, I reckon that things would have turned out differently for our participation had Bb. Pilipinas International Patty Betita been sent instead. After all, she was almost confident of getting the Bb. Pilipinas Universe 1991 crown until a late-filing Abayari entered the picture, became Candidate No. 3 and spoiled things for her.
