Many socialist countries, including the USSR, had provisions in their constitutions for recalling deputies by voters/citizens.
For instance, 1977 constitution of the USSR has
Article 107. Deputies shall report on their work and on that of the Soviet to their constituents, and to the work collectives and public organisations that nominated them. Deputies who have not justified the confidence of their constituents may be recalled at any time by decision of a majority of the electors in accordance with the procedure established by law
Was recalling of deputies ever done in practice in the USSR using the procedure outlined in article 107?
