Beirut port blast investigation head Judge Tarek Bitar resumed work on the probe in his office at the Justice Palace on Wednesday after he was officially informed of the Court of Appeal's decision to overturn a lawsuit filed by former minister Youssef Fenianos, the state-run National News Agency reported.
