In the final appeal Lord Campbell said:
No one can suppose that Lord Cottenham could be, in the remotest degree, influenced by the interest he had in this concern; but, my Lords, it is of the last importance that the maxim that no man is to be a judge in his own cause should be held sacred. And that is not to be confined to a cause in which he is a party, but applies to a cause in which he has an interest.
What does the adjective mean here? It can't be definition 1.2 'The lowest in importance or rank', which is logical, but contradicts the sacredness of the above maxim?
