Ex-spy Hermann Simm, in jail for treason, has contested a decision for denial of early release.
Simm's lawyer, Meelis Masso, is seeking to overturn a first-level court decision to free the former Internal Security Service employee, who spied for Russia. Instead of prison, Simm would be released to electronic tagging.
The court found that Simm had not served enough time and the nature of his crime, his behavior and the aim of the punishment did not merit an early release.
Simm was sentenced for treason and handing sensitive information to Russia about six years ago. He received a 12-year sentence. He was the first in a line of Estonian officials who were caught and prosecuted successfully for spying for Russia.
