Czech coal baron Pavel Tykac has won a legal battle to set up a special investigation into the “catastrophic failures” at the Callide C power station after long delays in the Queensland government’s review of the incident.

Mr Tykac’s family office, Sev.en Global Investments, acquired an interest in Callide C after it purchased a stake in InterGen in 2019, with the remaining shares held by Chinese energy companies. The Queensland government’s CS Energy also owns a stake.
