They also feature when discussing an [[Equally Weighted Vote]]; some voting methods which pass the "test of balance" can fail to produce an equally weighted vote when there are symmetrical ties; this includes many voting methods which pass the [[majority criterion]] in the two-candidate case; see [[Equally Weighted Vote#Notes]] for an example.
