Narrative:
Previous evening aircraft was released to maintenance to clear bleed 1 MEL due to expiration date. Maintenance [personnel] stated it was going to take 20 hours to restore the MEL. We were surprised to see that the aircraft was signed off for a kickoff flight the next morning; about 11 hours after aircraft was given to maintenance.during preflight the aircraft MEL was confirmed to have been restored and no abnormalities existed.after takeoff; during second stage climb; after takeoff inhibition logic expired; EICAS displayed bleed 1 fail and bleed 1 overpressure. Complied with QRH. Informed ATC and returned to departure airport; as bleed 1 overpressure prevented aircraft from entering icing conditions.during inspection of the aircraft by maintenance it was found that the bleed 1 valve was still in the secured position as dictated by the MEL. Improper maintenance procedures to ensure restoration of MEL.
