Here is my paper:

http://m-schulze.9mail.de/schulze1.pdf

The presumption that wins are always stronger that losses is
presumption (2.1.2).

Presumption (2.1.2) is needed to prove compliance with the
Schwartz criterion, the Smith criterion, and independence
of Smith-dominated alternatives.

Presumption (2.1.2) is not needed to prove transitivity,
resolvability, Pareto, monotonicity, reversal symmetry,
or independence of clones.
