After snatch, when she lifted 98kg on her third try, Punam, the current CWG champion in the 69kg division, took the silver medal.
Punam, however, got off to a poor start when she was unable to lift 95 kg in her first effort but succeeded in doing so in her second.
After the snatch was finished, she was ranked second behind Canada's Maya Laylor, who had lifted 100 kg.
Punam's clean and jerk, however, proved to be a letdown as she was unable to lift 116 kg in any of her three efforts.
After her final effort, Punam appealed the judge's decision, but it was denied, excluding her from the contest.
With a total lift of 228 kg (100 + 128), Laylor set a new record for the Games. Nigeria's Taiwo Liadi took home silver with a total lift of 216 kg (96 + 120). Maximina Uepa of Narau, who lifted 215 kg (96 + 119), won the bronze.
