Transfer of trustee voting rights to public trustee, enabling proxy appointment and inspection rights while limiting legal challenge. The statute transfers the exercise of voting rights and related powers in respect of shares held in trust from the trustee to the public trustee; the public trustee may appoint a government officer or the trustee as proxy, may abstain when beneficiaries or trust objects are unlikely to be adversely affected, may receive written views from the trustee but retain discretion, is protected from suit for abstention, and is entitled to inspect all books and papers available to a member. The section ceases to apply from the specified amendment.
