If an ineffectual clause appears in a legal document, it is reinterpreted in such a way that it is effectual.
For example, if one sells a house to his fellow and says to him, “I am
selling you this house with the stipulation that the fenced rooftop is
mine” - the fenced rooftop is his. The clause “rooftop is mine” is
redundant. It is already his, as we have learned before. Therefore, this clause is reinterpreted to give him additional rights.
Exactly which rights he gets is
subject to a dispute: either that he may project beams from the roof
into the adjacent yard, or that he may rebuild it if it collapses, with
the second view prevailing.
