The authority of the court extends, under defined conditions, to temporary suspension of positive commandments by shev ve-al ta’aseh.
Derash on the verse (Bavli) — not a formal named middah of the 13.
Under proper conditions the high court may suspend a Torah obligation by instructing passive non-performance.
