"There is [evidence from] the doctors that she is getting better…Is it right to delay the process and not to schedule a concrete date for finishing [the treatment]?," he said at the press conference in Kyiv on Wednesday.
At the same time the prosecutor general stressed that if Tymoshenko respected the law, the court process would start.
He also said that if she did not commit the crimes, let "the courts together with the lawyer prove it".
Commenting the opportunity of the premier to be treated abroad, the prosecutor said: "She should have a human conscience. She is a citizen of Ukraine. The law doesn't foresee treatment abroad. Let the Verkhovna Rada decide whether she could be treated abroad."
Pshonka also said that the blocking of the entrance and exit of the hospital on July 10 by MPs to hamper the transportation of Tymoshenko to the court was a political show.
"If the court decides it, she will be taken to the court - otherwise she won't," the prosecutor general added.
