23 There is another aspect to this second question. Just as the general rule is that the understanding must be issue specific to the particular transaction or documents, so in the case of litigation, the understanding must, I think, be in relation to the facts and the subject matter of the particular case. Legal proceedings have a spectrum of complexity. They can extend from the most simple issues through a range of complexity to quite involved and complex litigation. As a general rule, an action to recover a debt or to recover damages consequent upon a motor vehicle accident are examples of more simple forms of litigation, although even proceedings of that kind might involve a degree of complexity. However, an action such as this action where there are two defendants, where the issues against each defendant differ, and where there are real issues as to the nature of the duty of care, the standard of care, whether there was a breach of the duty of care and questions as to causation is an example of more complex litigation. It may be necessary to compromise against one defendant but not the other which only adds complexity to the decision whether or not to compromise the action. Thus, the question whether the person has the capacity to give sufficient instructions must be examined against the facts and subject matter of the particular litigation and the issues involved in that litigation.
