Stl
Special Tribunal for Lebanon (STL / TSL — Tribunal Spécial pour le Liban) research, drafting, and analysis. Use whenever the conversation involves the STL, the Hariri investigation, the assassination of former Lebanese Prime Minister Rafiq Hariri on 14 February 2005, the Ayyash et al. case (STL-11-01), the Merhi case (STL-13-04), the related-attacks cases (STL-18-10 against Salim Ayyash on the El-Murr, Hawi and Hamadeh attacks; STL-14-05 New TV S.A.L. and Al-Khayat contempt case; STL-14-06 Akhbar Beirut S.A.L. and Al-Amin contempt case), the Statute of the Special Tribunal for Lebanon, UN Security Council Resolution 1757 (2007), the UN-Lebanon Agreement of February 2007, the STL Rules of Procedure and Evidence, the application of Lebanese criminal law (Articles 314, 188-189, 270, 549 of the Lebanese Criminal Code, the 1958 Law on Increasing the Punishments of Sedition, Civil War and Inter-Confessional Strife), trial in absentia under Article 22 of the Statute, the STL's landmark February 2011 Interlocutory Decision on the Applicable Law (defining terrorism as a crime under customary international law), victim participation under Rule 86, sentencing, the closure of the STL on 31 December 2023 and the residual mechanism, or any STL document or case identifier. Enforces a verification-first discipline: every case-law, decision, indictment, filing, or judgment citation must be verified against stl-tsl.org (legacy site, archived) or legal-tools.org before appearing in any output. Foundational texts (UN-Lebanon Agreement, Statute, Rules of Procedure and Evidence) may be cited from project knowledge when present. Trigger this skill any time STL, TSL, Tribunal Spécial Liban, Hariri tribunal, Ayyash, Resolution 1757, or any STL case identifier appears in the request, even if the user does not explicitly ask for STL research.
