[T]he Also in civil law, the temporary situation that existed before the onset of the condition cannot be precipitated by retroactive property. Therefore, anyone who buys income property with retroactive effect is not entitled to restitution. Similarly, a buyer subject to suspensive conditions does not take the risk if the property is completely destroyed. However, the parties can, by mutual agreement, alter these effects. Faribault addresses other situations that are not expressly provided for by law: Reed J. agreed with the taxpayer because he felt that this case was similar to that of Perini Estate and that the retroactivity provided for by the parties in their agreement had to be applied: there are, however, reasonable times for this type of confidentiality agreement to be reissued and many will agree that this is not unethical or unusual. If this is the case, an agreement with a retroactive date can bring enormous benefits to all parties involved. Thus, many contracts and agreements are reviewed and negotiated after the start of trade or lively discussions, sometimes months. But backdating (or adding a retroactive date) can be a difficult business, perhaps even more so with NOA agreements because of their nature and content. The „Effective Date“ clause seems simple enough, but you have to be careful not to just insert it into your contract. Read the confidentiality agreement in its entirety and consider what logically cannot apply to the retroactive validity date. Today, both types of nullity have the same effects as a resolved condition.  They destroy the contract retroactively, as if the contract had never existed.
That is why all the comments made earlier on the conditions of dissolution apply, with the exception of the specific reservations we have made with respect to Article 1707 C.C.Q. Indeed, the provision applies fully to protect in good faith third parties who, after all, cannot know why a treaty is null and void. 5. … The Department considers that the sale price of each property sold is taken into account for income tax purposes where the seller has an absolute, but not necessarily immediate, right to payment. As long as a „pre-condition case“ [suspended condition“ in the French version remains dissatisfied, a seller has no absolute right to pay.
