Sen. Miriam Defensor Santiago was elected judge of the International Criminal Court by the Assembly of States Parties at elections held Monday, 12 December at the United Nations, New York.

Together with five other new judges, Santiago will take her oath of office this March, but will not immediately assume her post in The Hague, Netherlands, until the ICC calls her to report for duty.

Thus, it is likely that Santiago will remain as a senator in the next six months or even longer, depending on when she is called to The Hague.

The senator said she expects to play an active role as a trial judge in the impeachment case against Chief Justice Renato Corona, and to urge her fellow senators to pass the Reproductive Health bill, of which she is the author and co-sponsor. http:miriam.com.ph/newsblog/
