A right can not be exercised for the main purpose of violating public interests or damaging the others.
A right shall be exercised and a duty shall be performed in accordance with the means of good faith.

A person acting in defense of his own rights or the rights of another against immediate unlawful infringement thereof is not liable to compensate for any injury arising from his action. But if anything is done in excess of what is required for necessary defense, he is still liable to make a reasonable compensation.

A person acting to avoid an imminent danger menacing the life, body, liberty or property of himself or of another is not liable to compensate for any injury arising from his action, provided the action is necessary for avoiding the danger and does not exceed the limit of the injury which would have been caused by the said danger.
Under the circumstances specified in the preceding paragraph, if the person so acting is responsible for the occurrence of the danger, he is liable to compensate for any injury arising from his act.

In order to protect his rights, a person who restrains, seizes, or destroys the liberty or the property of another is not liable to compensate for any injury arising therefrom, provided the assistance of the court or other relevant authorities could not be obtained in due time and there was a fact that if the person did not act immediately, the exercise of his rights would be rendered impossible or manifestly arduous.

According to the provision of the preceding article, a person who restrains the liberty or seizes the property of another shall apply immediately to the court for assistance.
If the application mentioned in the preceding paragraph is dismissed or is not made in time, this person is liable to compensate for any injury arising from his action.
