Narrative:
About 10 minutes into the flight while climbing up through FL260; we got a number 1 engine oil filter bypass light flashing. We disconnected the autothrottle and slowly retarded the left throttle to idle. The light stopped flashing; but remained illuminated. We ran the checklist and shut down the engine. We coordinated with ATC for returning to the departure airport. Looking back; we did not declare an emergency with ATC and this was a mistake. On return; we completed all the necessary checklists and landed uneventfully. This problem was written up on the previous flight; but maintenance could not duplicate.
