The expression 'alter to a substantial degree' in s 41 of the Land Use Planning and Approvals Act 1993 (Tas) is to be given the broadest possible scope, having regard to the statutory scheme requiring public exhibition following such alteration. An alteration that changes the essential core of a proposed amendment may still be an alteration to a substantial degree. The Commission's power under s 41(a) extends to directing inclusion of land not within the original draft amendment. Section 41A(1)(b) requires the Commission to specify the way the amendment is to be altered, not to effect the actual alterations itself.
