The European Commission on Monday has launched an infringement procedure against Poland over its Supreme Court legislation, the commission said in a statement.
"The Commission is of the opinion that these measures undermine the principle of judicial independence, including the irremovability of judges," the statement reads.
The commission expressed concern over the new law forcing 27 out of 72 Supreme Court to retire as it lowered the retirement age of Supreme Court judges from 70 to 65.
In December 2017, the European Commission proposed to invoke Article 7 of the Lisbon Treaty over Poland's controversial judiciary legislation, paving the way for sanctions against the country and suspending some of its rights as an EU member.
The European Commission opposed the Polish legislation since it stipulates discrimination against individuals on the basis of gender by providing for the different retirement age for female and male judges. In addition, the Polish law is criticized over undermining the courts' independence by giving the minister of justice the discretionary power to prolong the mandate of judges who have reached retirement age, to dismiss and appoint court presidents and exert influence on individual judges through "vague criteria."
