Criminal rap vs Rodrigo Duterte puts justice system to tough test - lawyer.

MANILA -- The criminal complaint lodged against former President Rodrigo Duterte is a test of the country's justice system, a lawyer of ACT Teachers Rep. France Castro said Tuesday.

Lawyer and professor Antonio La Vina, another MAD convener and counsel of Castro, said that despite issues and problems, they would like to believe still that the rule of law governs the country.

However, like Domingo, he leaves the decision on Castro's complaint to the prosecutor.

'We're sticking strictly by the rule of law here. We can say that while very slow, even at the height of big problems, we are able to move the wheels of justice,' La Vina said.
