Where a trustee exercises a discretion, it may be impugned on a number of different bases such as that it was exercised in bad faith, arbitrarily, capriciously [3] , wantonly, irresponsibly [4] , mischievously or irrelevantly to any sensible expectation of the settlor [5] , or without giving a real or genuine consideration to the exercise of the discretion [6] . The exercise of a discretion by trustees cannot of course be impugned upon the basis that their decision was unfair or unreasonable [7] or unwise [8] . Where a discretion is expressed to be absolute it may be that bad faith needs to be shown [9] . The soundness of the exercise of a discretion can be examined where reasons have been given, but the test is not fairness or reasonableness [10] .
