I assume you mean the speed tables down Birdcage?
As they are not light controlled with ambers or traffic lights and there are no road markings (ala zebra, pelican or toucan crossings) there is no implied requirement to stop to give way to pedestrians waiting to cross as there is in the case of the aforementioned crossing types.
However, on the flip side, they are signed as a raised pedestrian crossing, and are intended to make the crossing of pedestrians more predictable and controlled for other road users. Given that pedestrians always take priority when on the road, fault for clipping someone at one of these locations I would assume would always fall on side of the cyclist or road user under the pretence of "due care and attention" - they are raised and signed areas where traffic should expect pedestrian cross traffic. That is, unless, you had numerous witnesses who could say that the pedestrian themselves simply walked out in front of you without themselves checking that it was safe to cross making the (hypothetical) collision unavoidable on the part of the road user.
Thats my understanding at least.
