Milas was close to Marko Veselica and was active in the Croatian Spring in the early 1970s. In 1972, the authorities of communist Yugoslavia charged Milas with "actions against the state", arrested and spent six months in jail awaiting trial.[1] He was released to prepare his defense, and subsequently fled to Austria where he received the status of a refugee. Yugoslavia sought his apprehension, which Austrian courts denied. He was tried in absentia in Yugoslavia and received a two-and-a-half-year prison sentence.[1]
On May 28, 1995, President Tuđman awarded him with the Grand Order of King Dmitar Zvonimir. Also in May 1995, the function of the Keeper of the State Seal (Croatian: Čuvar državnog pečata) was created,[3] and President Tuđman named Milas to the position[1][2] on May 6, 1995, where he remained until February 1, 2000. As of 2019[update] no other person was named to the position after Milas.
Milas was elected to Sabor again in the October 1995 election.
Milas gained considerable notoriety in the Croatian public after he publicly expressed his opinion that in the West, brain is valued in kilograms.[4][5]
