MANILA - Six Supreme Court magistrates will testify against Chief Justice Maria Lourdes Sereno when the House justice panel hearings on the impeachment complaint resume on January 15, a lawmaker said.

Oriental Mindoro Rep. Rey Umali said the number of justices willing to speak against the Chief Justice shows the dissatisfaction with the Supreme Court leadership.

"When about 8 at least are more or less not too satisfied with the leadership, then we have a leadership issue. The Supreme Court is divided," he said.

Among those expected to appear in the hearing are Senior Associate Justice Antonio Carpio, Justices Lucas Bersamin, Samuel Martires, Mariano del Castillo, Andres Reyes, and probably Diosdado Peralta.

Associate Justices Noel Tijam, Francis Jardeleza, Teresita Leonardo-de Castro and retired justice Arturo Brion already testified against Sereno last year.
