In Papua New Guinea, the proliferation of social problems related to polygamous marriages has led to one social justice advocate  calling polygamy a “social evil”. It certainly leads to some serious problems. 65% of PNG’s female prisoners  are convicted of a crime related to polygamous marriages, specifically, the murder of a fellow wife. Julie Soso, a female politician, proposed bill  in 2012 to outlaw polygamous marriages. In 2014, the Civil Registration Act was amended to make “bigamous or polyandrous” (sic) customary marriages illegal. (Polygamous formal marriages were already outlawed.)
