If yes, we can implement this by passing a Special Resolution at the first AGM restricting the powers of the directors. (see Article 23#1 in the draft Articles)
For people that aren't familiar with the terminology, a "Special Resolution" is a vote at a general meeting requiring a 2/3 majority (I think it's 2/3, it could be 3/4, whatever it is, it's more than 1/2 which is what's required for an "Ordinary Resolution").
