In April 1931, two weeks following birth of the Republic, Tellería signed a joint manifesto calling for a common vasco-navarrese representation, aiming for “reivindicación de nuestras libertades y reconocimíento de nuestra personalidad historica”; other signatories included other traditionalists like Antonio Pagoaga, Julián Elorza, marqués de Hormazas and the Baleztena brothers, though there was no Basque nationalist who co-signed.
