It's a good decision. It has set precedent for all future elections.
PTI shouldn't challenge this decision and any late entry of a single presiding officer should be a basis of reelections.
Also, if a few polling stations are found with low turn out, that is also one of the reasons now sanctioned by EC for a reelection.
We should all be happy. In the past, bags were found with garbage and newspapers and still no repolling was ordered.
This is better for PTI's future.
