These can be reduced to several classes: (1}Incentive to crime, which is a claim that cannot be sustained, therefore, on a bond for compounding a crime or for procuring a pardon. (2}Indecent consideration, or mischievous consideration, is an obligation or engagement which is either prejudicial to the feelings of a third party, or offensive to decency or morality, is void.

Law does not compel the doing of impossibilities.
This legal maxim is of the latin origin meaning the law does not compel you to do anything vain or impossible. It is a very old maxim that was discussed by Justice Owen in Hughey v. JMS Development, meaning laws do not compel a man to do something he cannot possibly perform. Here, the word “lex” literally means a system of law, “non” means does not, “cogit” means to compel, “ad” means to, and “impossibilia” means impossible.
Law has regard for equity.
The legal maxim is of latin origin meaning law considers equity. This maxim preaches that, in applying law, a tribunal should consider and incorporate principles of equity.
Statement of falsehood
The legal maxim is of latin origin meaning a statement of falsehood or, in simpler words, a false statement. Suggestio falsi is feeding someone lies intentionally to benefit out of it and put the other person in loss. This act amounts to a fraud when the party was bound to disclose the truth in the first place to keep the fairness of the contract. Suggestio falsi is a ground to rescind an agreement or to avoid carrying it to execution.
