Repoll was ordered at Bauna booth of Dharchula following complaints that the presiding officer along with his team left the booth while the EVMs were still on, Uttarakhand's Chief Election Officer Radha Raturi said.
As per Election Commission guidelines, the presiding officer cannot leave a booth without switching off the EVMs, she said, adding that the repoll will be held tomorrow.
The booth is located in the interior of Pithoragarh district.
However, the ruling Congress rubbished the charges of rigging levelled by the BJP saying the opposition is frustrated in the face of imminent defeat.
"The BJP is levelling unfounded allegations against the Congress out of sheer frustration as it can foresee its defeat," CM's media in-charge Surendra Kumar said.
