If Jaylynne agrees to cut down the tree for the money, the deal does not come with any conditions: Jaylynne is required to fulfill her side of the bargain. A purely potestative condition if volam, which provides or not to the promiser an unlimited choice on performance – “I give you R100 if I wish” – clearly does not create any obligation, but the situation is different if the fulfillment depends on the will of the promise (where Andrew Bianca, for example, gives an option to buy his farm). A state of power can be negative, like when Andrew Bianca makes a gift, provided Bianca does nothing. A promise subject to a condition of negative power is only achievable with the death of the promise, for only then will the condition be fulfilled. On websites, validity dates are often present in the General Terms and Conditions of Sale and the Privacy Policy. Unless a company makes a particular effort to enter into an individual agreement with an end user or a group of highly specialised end-users, the general terms and conditions of sale (or terms of use) and a privacy policy apply to all users of a specific website or Internet platform. One of the fundamental principles of contract law (pacta sunt servanda or untouchable contract law) is that agreements concluded seriously must be applied, but that agreements which clearly harm the interests of the Community as a whole, whether they are contrary to law or morality (contra bonos mores) or if they are contrary to social or economic expediency. is not forced. These contracts are illegal for reasons of public order. The law considers that illegal or illegal contracts are either and therefore unenforceable, or valid, but unenforceable.
The effect of a contract or obligation is often conditioned on the truth of an acceptance made by the parties on a past or present fact. For example, if Johann and Piet negotiate a contract to buy and sell a painting, Johann may stipulate that he will only make the purchase if the painting is an original rembrandt. They call an expert. If their presumption is confirmed, the contract continues, otherwise the contract will be deleted. Similarly, Fourie vs. CDMO Homes[70] was CDMO`s sale of land adjacent to a river in Fourie, the offer of which was subject to the following condition: that there be pumping rights on the river. Although the parties are not sure whether this is the case, they have reached their agreement on the assumption that the pumping rights are in place. Secretary Clinton`s ethics agreement at the time did not prevent other State Department officials from dealing with or contacting the Clinton Foundation.
