WASHINGTON — The panel investigating the Central Intelligence Agency’s search of a computer network used by the Senate Intelligence Committee found that five agency officers had acted in good faith during an episode marked by confusion and poor communication, and should not be punished.

The accountability board, whose findings were made public on Wednesday, overturned the conclusions of the C.I.A. inspector general, who had determined last year that the five officers acted improperly when they searched files used by the Intelligence Committee during its investigation of C.I.A. torture.

The computer search raised questions about the separation of powers and fractured relations between the C.I.A. and the Senate oversight panel, which last year released its scathing report about the agency’s detention and interrogation program during the George W. Bush administration.
