一篇关于波兰要求德国赔偿的文章中
About two-thirds of Poles support reparations, according to a recent
poll. The parliamentary analysis has been delayed, ostensibly because
of its complexity. Tensions within Pis are simmering after the
president, Andrzej Duda, a former party member, last month blocked
a law sacking supreme-court judges.
请问文中最后一行的 sacking 是什么意思呢？
