Bolivian judges say proposed constitution illegal

Legal holes and inconsistencies also riddle the document so it cannot be put to a referendum this year as planned by Morales, the judges said.

"The project is legally stillborn," they said.

Morales and opposition governors have tried to resolve their differences but talks stalled this week on how to revise the constitution to incorporate the provinces' autonomy declarations and divvy up natural gas revenue.

The governors and Morales said this week they would face referendums that could remove them from office if they fail to reach a national accord soon to end the protracted political deadlock. (Reporting by Armando Perez Fernandez and Terry Wade; editing by Fiona Ortiz and Vicki Allen)
