The Pasig City Prosecutor’s Office has dismissed the charges filed by police against environmental activist Jonila Castro over her participation in a September protest outside a building owned by contractors Curlee and Sarah Discaya.

The National Union of People’s Lawyers (NUPL) announced the dismissal late Friday through a Facebook post by its president, Atty. Ephraim Cortez.

Cortez cited the prosecutor’s resolution, which found that police failed to identify who actually led the protest — where demonstrators reportedly hurled mud and spray-painted slogans at the office of St. Gerrard Construction.

“Aside from naming Jonila as among those who joined the protest, the complainant failed to allege or prove that she was a leader of the action,” the NUPL said.

Cortez called the case against Castro “an obviously baseless complaint” meant to intimidate and silence dissenters.

Castro, spokesperson of the group Kalikasan, earlier said protesters went to the Discaya building to express public outrage over alleged large-scale corruption in flood-control projects.

“We wanted to show the Discayas the people’s anger — that while we wade through floods and mud, they’re swimming in money stolen from the public,” Castro said.

Cortez also urged authorities not to misuse the Public Assembly Act to suppress legitimate protest, stressing that freedom of expression and peaceful assembly “may only be curtailed by a clear and present danger.”

He said filing criminal charges against individuals for joining rallies without a permit, as in Castro’s case, is an undue restriction on constitutional rights.
