 Huepe soon expressed publicly his rejection to the coup and its interruption of the Chilean democratic tradition by signing the so-called Statement of the Group of Thirteen.As a consequence of his opposition to the military dictatorship, he was later detained and sent to the political prisoner camps of Tres Álamos and Ritoque for three months.He was then exiled, in 1975, living in England and Venezuela until he was allowed to return to Chile in 1984, as the dictatorship slowly started to open-up politically.
