This sentence conflates a prison transfer with parole/early release.

Contemporary reporting from August 2018 says Koufontinas was moved from Korydallos to an agricultural prison in Volos and that the move followed a decision by a transfers committee overseen by the Justice Ministry. It does not say he was paroled. A separate Associated Press report says the government defended the move, that Koufontinas "will continue to serve his sentence normally," and that he would only have the right to apply for early release in 2021. That directly contradicts the idea that a parole request had already been approved in 2018.

So the accurate description is that he was transferred to a lower-security agricultural/open prison while remaining in custody, not released on parole.

The chronology and issuing authority are misstated here.

Multiple contemporaneous reports say that the intervention came from the Lamia prosecutor’s office / prosecutor of first instance, after a request from the hospital’s doctors. Those reports also place the order on 23 February 2021, while noting that Koufontinas had begun refusing liquids from the evening of 22 February 2021. So the order was issued the next day, not “a few days later,” and it was a prosecutorial order, not an order issued by “the courts.”
