Judge Norberto Garcia Vedia visited Maradona at the private psychiatric clinic where his family admitted him against his will last week, and determined he was not fit to decide whether to discharge himself.
"He is no condition to decide for now," Garcia Vedia told Reuters Television. "He is suffering a crisis."
Maradona's family transferred him on Sunday from an intensive care ward where he was treated for heart and lung problems to the Clinica Privada for drug addiction
His family doctor has described Maradona's treatment as a "last chance" to kick his cocaine habit. Maradona, 43, has spent most of the past four years living at a spa in Cuba where he has been undergoing a drugs rehabilitation program.
While on a visit to Argentina last month, he was rushed to hospital with a swollen heart and breathing problems and he spent two weeks in intensive care, including a week on an artificial respirator.
After a slow recovery, he suddenly discharged himself only to be seen playing golf hours later. Within days he was back in hospital with breathing problems.
