Lluhí was not included in the government initiated on 24 January 1933.^{[citation needed]} He left the Esquerra Republicana in October 1933 to found the Partit Nacionalista Republicà d’Esquerra, with the old followers of L'Opinió.^[2] He later led this group back into the Esquerra.^[1] He was appointed Director of Justice on 3 January 1934 in the first government of Lluís Companys.^[2] He was suspended from the government after the attempted revolution that followed the Asturian miners' strike of 1934.
