Requirement for Traversing Restriction
Note:
The rule requires a written statement when traversing a restriction requirement, and failure to do so will be treated as an election without traverse.

A traverse is a request for reconsideration of a requirement to restrict that must include a written statement of the reasons for traverse, distinctly and specifically pointing out the supposed errors upon which the applicant relies for concluding that the requirement is in error. The absence of any statement indicating whether the requirement to restrict is traversed or the failure to provide reasons for traverse will be treated as an election without traverse.
