27 In this case, both applicants held the belief for some 30 years or so, that they should have received a greater share of the estate than that which is provided for them by the testamentary dispositions. They did no more than complain about this to their mother. Although they received from their mother the assurances to which I have referred, both applicants knew that she could do no more than try and exert moral influence over the trustees and their other brother. During the whole time that the applicants' mother was a widow, the applicants' complaint was not mentioned to the trustees, despite continuous opportunity to do so. It is clear that the applicants were not content to accept, without question, that their mother would try and exert influence over the trustees and the other brother or, if she did, that it would be successful, for they not only raised the issue with their mother on more than one occasion, but they also took the matter to a solicitor 14 years ago. In consequence, by that time at the latest, the applicants were aware, in general terms, of the right to challenge testamentary provisions but made a conscious choice not to do so. In these circumstances it cannot be said that there has been shown a satisfactory explanation for the very long delay.
