Is it legal to double your opponents with the express purpose of getting them to change to another suit which you have a better chance of defeating? One person in our club often seems to do this and will 'double' with only a couple of poor cards in the suit doubled, but with a hand strong in the suit which he hopes the opposition will revert to. This seems like dirty play to me.

It would only be illegal to double like this if the person (lets call them X) had an agreement with his partner to do so and there were regulations that did not permit such agreements. But it sounds as if X doubles like this regardless of who his partner is, so there is no real partnership agreement, just X's individual style. And most regulations allow any agreements about doubles (after the first round of the auction).
If X's partner is aware of this style of doubles then the partner should explain it to the opponents. If the club find that X's style of doubles is disruptive they could ask X to change.
My advice is if you play against X, explain to your partner about X's style of doubles, and suggest that you should be reluctant to "run" when X doubles; and learn to redouble!
