There seems to have been a misunderstanding in the initial post here, which said that the appeal had been turned down and that the execution was set for June 23rd. That is not the case.

In fact what has happened is the the appeal against the sentence has been postponed. It is the appeal which is due to take place on June 23rd.

Bad enough, but not quite the same thing.

Here is the Amnesty International link about all this.
