“… While constructing the words used can be difficult, it is not a reason to keep them too vague or uncertain to be applied if the fair meaning of the parts can be extracted. However, when two clients withdrew in the past three years, the company attempted to recover commissions, but the consultant argued that the refund clause of the agreement was invalidated by uncertainties because it had not clearly defined how to calculate the amount to be repaid. This was also explained by the Court of Appeal in order to compel debtors to “take all measures in their power that are able to achieve the desired results… A prudent, determined and reasonable [obliged] who acts in his own interest and wishes to achieve this result” (IBM United Kingdom Limited/Rockware Glass Limited  FSR 335). It is generally accepted that someone who promises to do his best does not guarantee the result, but will be willing to make some financial expenses if he tries to do so. Section 29 contains the importance of an agreement which, at first glance, should be clear, as demonstrated in Kovuru Kalappa Devara vs. Kumar Krishna Mitter , but the effect can be granted to the contract if its meaning is found with reasonable clarity. If that were not possible, the treaty would not be applicable. Only difficulties of interpretation are not considered vague.

An agreement providing for future pricing by the parties or by a third party can be insured and applies in accordance with Section 29.
