Tăriceanu has been accused by President Băsescu of interfering with justice in Dinu Patriciu's benefit.
On 24 January 2006, Monica Macovei, then Minister of Justice, made public a meeting with Tăriceanu which took place 7 months before (in June 2005), and to which Tăriceanu invited Dinu Patriciu. Patriciu complained to Macovei about alleged procedural problems regarding his case. Macovei accused Tăriceanu of interfering with justice. On 20 February 2006 Tăriceanu declared on TVR1:" I recognise my fault. I didn't act correctly. But I didn't influence justice."(in Romanian) "Îmi recunosc vina. Nu am procedat corect. Dar nu am influenţat justiţia"[7]
Elena Udrea recalled that, while she was Presidential Counsellor, she saw a note written by Tăriceanu. In a few days President Băsescu found the note and made it public, saying that "The Prime Minister suggested to me a partnership, but, unfortunately, with our oligarchies"(in Romanian) "Domnul prim-ministru îmi propunea un parteneriat, dar, din păcăte, cu oligarhiile noastre". The note was about a complaint from Petromidia about the 27 May procedure problems:
Dear Traian, 1. I send you annexed a document released by Petromidia, regarding the ongoing investigations. 2. If you have the opportunity to speak at the Prosecuting Magistracy about the subject?[8]
In May 2007, Patriciu won a lawsuit against the Romanian Intelligence Service (SRI), which illegally tapped his phones for two years. He received from SRI 50,000 RON as moral prejudice.[9]
