I edited my post to remove the impression that Inyo unilaterally decided to add the permit requirement for summit to Portal via the MT.

The last 400' of the MR is in SEKI. My INF boss told me that SEKI was worried about people in that section being at risk, but they had no way of knowing anything about them in case of a problem. Maybe they were primarily concerned about newbies, I don't know. SEKI wanted some sort of a permit system in place, but they couldn't issue them because these people start in from INF, not SEKI. So they got INF to do it.

SEKI wanted it, and INF had the authority.
