Actually, under Douglas Woodall's framework, it could be argued that
Approval fails Pareto. (Approval is considered a rank ballot method where
all ranked alternatives are approved and the truncated ones are
disapproved. So if every vote is x>y, the outcome is a tie.)
You don't have to use his scheme of course, but I would say that there
isn't much agreement on how to analyze Approval. The tricky thing is that
you don't want to analyze it in such a way that it satisfies Condorcet,
for instance.
