MANILA - Comelec Commissioner Christian Robert Lim on Friday confirmed that he will be resigning from his post as chairman of the poll body's Campaign Finance Office (CFO).

"Will tender on Monday," Lim said in a text message when asked to validate rumors that he is set to leave his post.

Asked about the reason behind his resignation, he simply replied: "Di acceptable ang policy shift."

He declined to discuss more.

Lim's resignation comes amid the controversial decision of the Comelec en banc to grant the request of the Liberal Party (LP) to extend the deadline for the filing of Statement of Contributions and Expenditures (SOCE) until June 30.

Lim, along with Chairman Andres Bautista and Commissioner Luie Guia, voted against the extension of the deadline.

As chairman of the CFO, Lim expressed his strong opposition to grant the LP's request in a memorandum submitted to the en banc Wednesday.

Lim said the 30-day period of filing from the day of the election is a "hard deadline" set by Section 14 of Republic Act 7166. He added that the commission has not been given authority by Congress to fix the period of filing for SOCE.

As such, "any extension given by the Commission is tantamount to an amendment of the law," Lim said.

"To grant the extension would not only be unfair to other candidates and parties who complied within the prescribed period but also would be a reversal of the Commission's own resolution on the matter," he added.

Lim, however, was not present during the special en banc session Thursday afternoon, when they were outvoted 4-3.

Before the meeting, Lim did not also attend the last two sessions of the en banc.
