Voting technicals

when I was looking for confirmation if voter turnout makes an impact ( ie Scheme letters going into the recycling bin unopened) I found very interesting info online which contradicts my initial assumption:

Allens Handbook on Takeovers:

"...Blocking of scheme of arrangement

A person who owns or has voting control over 25% or more of a company’s shares can unilaterally block the approval of a takeover conducted by a scheme of arrangement, because one of the scheme voting thresholds is approval by at least 75% of the votes cast on the scheme resolution. (In practice, a person can normally block a scheme with less than a 25% interest given voter turnout at scheme meetings is often substantially lower than 100%.)..."
