The Sunnewspaper will not face censure for its role in the return to Britain of Great Train Robber Ronnie Biggs.
The Press Complaints Commission's decision - published on the newspaper's Website - said it rejected complaints.
It said the claims it had not acted in the public interest or that Biggs had benefited from its reports were not "sustainable".
An investigation was launched into the affair in May this year after the Sunchartered a private jet to bring 71-year-old Biggs back from his home in Brazil.
The PCC concluded: "To have censured the newspaper would have indicated that the actions of the newspaper were not in the public interest, and that money was being channelled to Biggs in order, in some way, for him to benefit from his crimes. Neither was sustainable."
The Commission's ruling said it was impossible to conclude that Biggs's return to Britain was against the public interest.
It added: "In this case, the result of the newspaper's action was to return to justice a wanted criminal who had been at large for over three decades."
The Sun'seditor Mr David Yelland said he welcomed the adjudication.
"It is a complete vindication of the Sun'sdecision to bring Ronnie Biggs to Britain to face justice after 35 years on the run," he said.
"The return of Biggs to Belmarsh was one of the greatest operations carried out by a national newspaper acting in the public interest for many years," Mr Yelland said.
