In its order, the court said the invitation was insufficient reason for Yingluck to leave the country at this time and therefore her request, filed with the court earlier this week, was turned down.
A copy of the court order was seen by The Nation Wednesday.
European Parliament members Elmar Brok and Werner Langen, in their letter dated October 7, invited Yingluck to exchange views on the Thai political situation either in Brussels, Belgium, or Strasbourg, France.
The invitation letter was just publicised last week.
Yingluck is facing a legal case to be tried by the Supreme Court in connection with her government’s corruption-plagued rice-pledging scheme.
