If an expert re-measures a techum that was previously established and changes it (enlarging in some places, shrinking in others), are both the enlargements and reductions accepted?
Synopsis
When a new expert re-measures an established techum and changes the boundaries, his ruling is accepted in both directions — even in places he expanded the techum. The Rema records a dispute about how to handle mismatched measurements in different directions.
