It is dodgy in theory. There are both fish and newts in the pond - the fish were put in there first in our less wildlife-aware days. The adults coexist happily, so far as we can tell. The newts breed with gusto and seem to multiply each year, so enough of their spawn survives to be viable. There is lots of cover in the pond so we assume some cunning or lucky taddies manage to stay out of trouble each year. It's the frogs that have to worry - the newts as well as the fish eat their spawn.
