The following principles apply with regard to all of the required separations mentioned in the previous chapters. If the person who was required to separate failed to do so, and the neighbor saw the disturbing factor and yet remained silent, he is considered to have waived his right to protest, and he may not raise a protest later to require him to move. The above applies provided it is obvious that he waived his right to protest - e.g., he immediately helped his colleague in performing this activity, he told him to do so, or he saw him perform this activity next to him and remained silent and did not take issue with him. The general principle is: Whenever a person establishes a right to perform a damaging activity, that right is entrenched as his own, as has been explained. When does the above apply? When he established his right to perform any damaging activity with the exception of the four mentioned in this chapter: smoke, the odor of a latrine, dust and the like, and the shaking of the ground. For with regard to these activities, one can never establish his right to perform them. Even if the person suffering from this damage remains silent for several years, he may come and force his neighbor to distance himself. Similar concepts also apply with regard to the invasion of privacy in places where it is required to build a partition. He may compel him to build a partition whenever he desires, as explained. Why are these damaging factors different from all other damaging factors? Because a person's disposition will never be willing to bear these damaging activities, and we assume that he has not waived his right to protest. For the damage is of an ongoing nature. If, however, a kinyan was concluded, confirming that he waives his right to protest these activities, he may not retract.
