Claim
Carlo Metta was officially exonerated.
Correction

The appeal decision reversed the penalty for lack of proof, but it did not officially clear Metta of wrongdoing.

Full reasoning

The official appeal ruling does not say Carlo Metta was innocent or “exonerated.” Instead, the Appeals Commission wrote that the league manager’s analysis supported the cheating claim and that the original decision was made in good faith, but that with the tools available it was not proven “without a reasonable doubt” that Metta broke the rules, so the decision should be reversed.

That is a reversal based on insufficient proof, not an official declaration of innocence. Calling this an “official exoneration” overstates what the commission actually decided.

    The analysis performed by the league manager also supported the claim that the accused player used Leela... Thus, we do not think that it was proven without a reasonable doubt that Carlo Metta broke any rules and the decision made by the league manager should be reversed.

Claim
That same year, the Italian team was relegated to a lower league where no-one powerful in European Go politics cares to look anyway.
Correction

Italy was not relegated after the 2017/2018 season: the official 2018/2019 PGETC lineup and standings place Italy in League A, the top division.

Full reasoning

The official PGETC records for the 2018/2019 season place Italy in League A, not in a lower division.

  • The tournament’s September 2018 opening announcement lists League A as including Italy.
  • The official 2018/2019 League A table also shows Italy competing there throughout the season.

So the article’s statement that Italy had already been relegated to a lower league “that same year” is contradicted by the tournament’s own published records.

Claim
Metta went on a 9-0 streak against opponents matching his OTB level in the 2018/2019 season
Correction

Official PGETC results show Metta lost at least one 2018/2019 game, so he did not go 9–0 that season.

Full reasoning

The official 2018/2019 PGETC Round 7 results record a loss by Carlo Metta:

  • Hungary vs. Italy, 12 March 2019
  • Dominik Bővíz vs. Carlo Metta — W+Resign

Because Metta is recorded as losing that game, he cannot have had a 9–0 record for the 2018/2019 season.
