Have you already come across one law that allows a person to file charges to annoying people? This law, aside from being tongue-in-cheek, is rather ambiguous as it lacks specific definition. Unlike other laws that prohibit a person to do this and that, unjust vexation seems to send mixed signals that only bring confusion to people. It is considered a catch-all provision, because it has no specific meaning that will clearly provide laymen a deeper and better understanding of the law.
For instance, if you find your neighbour annoying and what he/she does violates this law, he will be “punished by arresto menor or a fine ranging from 5 pesos to 200 pesos, or both.” There are various cases in which this ambiguous law has been applied, but its lack of specific definition will make one wonder whether they are already crossing the lines or not. For instance, a person can be convicted of unjust vexation for simply interrupting or disturbing a ceremony of a religious character.
This law can be found in Article 287 of the Revised Penal Code:
" Art. 287. Light coercions. — Any person who, by means of violence, shall seize anything belonging to his debtor for the purpose of applying the same to the payment of the debt, shall suffer the penalty of arresto mayor in its minimum period and a fine equivalent to the value of the thing, but in no case less than 75 pesos.
Any other coercions or unjust vexations shall be punished by arresto menor or a fine ranging from 5 pesos to 200 pesos, or both."
