MANILA - A Manila Times reporter denied Monday he revealed his sources in an article that was used in the impeachment complaint against Chief Justice Maria Lourdes Sereno.

Journalist Jomar Canlas told lawmakers he did not disclose to lawyer Lorenzo Gadon, who has lodged the complaint against Sereno, his source. He denied that his source was Associate Justice Teresita De Castro.

"I have never revealed to anyone my source or sources in the article, who suffice it to say are reliable and well-placed sources," he said in a House justice committee hearing.

"I also hereby categorically deny that Justice De Castro was my source in the news article entitle ‘Justice blasts Sereno over TRO mess'," he added.

The reporter was asked to attend the impeachment proceeding after Gadon told lawmakers in a hearing last week that he confirmed Sereno’s alleged tampering of a temporary restraining order recommended by De Castro in 2013 through Canlas.

De Castro has earlier denied giving information to Canlas: "I have never released to Jomar Canlas any information, report, or document regarding the work of the court."
