MANILA (2nd UPDATE) - The Bureau of Immigration (BI) said Wednesday it cancelled the visa of Australian nun Patricia Fox and ordered her to leave the Philippines in 30 days, citing her alleged partisan political activities.

Fox's alien certificate of registration was also deactivated after intelligence agents found photos of her alleged participation in an anti-government rally, said Immigration Commissioner Jaime Morente.

“She was found to have engaged in activities that are not allowed under the terms and conditions of her visa,” Morente said.

Fox's lawyer Jobert Pahilga slammed the BI's order saying it violated the nun's right to due process, as she has yet to file a counter-affidavit to refute allegations against her.

"What we received yesterday was the supplemental report of the intelligence division. We were given 10 days to supposedly file our counter affidavit. That's why we were surprised there was an order by the BI to forfeit her visa," he said.

The lawyer insisted that Fox has has only been engaged in missionary work with the farmers, indigenous peoples, and the poor, not in political activities. He said they will be questioning the BI order before the proper court.

The 71-year-old, who had been doing missionary work in the Philippines for 3 decades, may still return to the country but only as a tourist, BI spokesperson Antonette Mangrobang said.

President Rodrigo Duterte said last week that he had Fox investigated for alleged "disorderly conduct" but clarified he did not order her arrest.

Fox was detained just a day after European Socialist Party official Giacamo Filibeck was barred from entering the country and deported for criticizing the government.

'Cowardly'

Former Human Rights Commissioner Etta Rosales slammed what she calls the President's "deportation spree" and said Fox's expulsion would go down as one of the Duterte administration's most cowardly acts.

"Why is President Duterte so allergic to human rights advocates? Duterte is dragging the whole country to a dark era where human rights defenders are threatened and sent away while violators are placed in power," she said in a statement.

"With the deportation spree, Duterte is in danger of projecting himself - contrary to his machismo and bravado - as a weak leader, afraid of his own shadow and unable to cope with the rigors of democratic rule, losing his credibility altogether in the complex and diverse field of governance and rule of law," she added.

Opposition Sen. Risa Hontiveros also blasted the government for expelling a 71-year-old nun while disregarding threats to the country's sovereignty in the West Philippine Sea.

"We deport missionaries but allow China to continue its incursions unchallenged?" she said.

Sen. Bam Aquino, meanwhile, said he would move for a Senate investigation into Fox's expulsion and possible abuses in the state's power to deport foreign nationals.
