The decision was taken during a meeting convened by PPA Mahila Council president Kenyir Ringu here yesterday, a party communique said today.
The party has put gender equality and women empowerment on its priority list and has decided to oppose polyandry along with polygamy, the release said.
"The rules will be applicable and strictly followed in future and we will continue our campaign against the practice of plural marriage.
"If any candidate is found violating the monogamous norms, they will have to surrender their party membership as well as the post to which they have been elected," Ringu said.
"It is the PPA which gave a ticket to Nyari Welly, who is even today seen as an iconic legislator and a voice for gender equality in the state," Ringu added.
