[2] Perhaps due to the sensitive nature of future Polovinskas' career, very little is known about his family or early life.

[5] During his tenure, Polovinskas discovered the so-called saccharin scandal – smuggling of foodstuffs to Soviet Russia in diplomatic packages which led to the resignation of Minister of Foreign Affairs Juozas Purickis in December 1921.

After many Lithuanian officers refused to lead the rebellion, Polovinskas became the military leader of the Klaipėda Revolt.

He commanded the "Ypatingosios paskirties rinktinė" (Special Purpose Force), which was formed in Kaunas and marched into the Klaipėda Region in early January 1923.

[3][5] On 17 January, Budrys became the deputy of Antanas Smetona, the Lithuanian government's representative to the Klaipėda Region.

However, after the failure of Lithuanian parties in the first elections to the Parliament of the Klaipėda Region in November 1925, Budrys resigned from the governor's role.

[8] On 12 January 1927, Budrys became the chief of the Lithuanian Political Police (predecessor of the State Security Department of Lithuania) under the Ministry of Internal Affairs.

[9] Taking the post soon after the December 1926 coup d'état, he helped President Antanas Smetona to establish his authoritarian regime and suppress any counter-coups.

The Political Police discovered that retired General Konstantinas Kleščinskis was spying for the Soviet Russia.

His gravestone depicts the coat of arms of Klaipėda, stylized sea waves, and the Jagiellon Cross.
