He was set to try his hand at politics once more as a candidate for the European Parliament, again from the SLD party, in the 2014 elections. Ultimately he decided not to take part, as his son-in-law was also running for office but via an opposing political party. In 2018, the conservative ruling Law and Justice party of Poland — mirroring similar efforts from 2007 — tried to vote through a law that would collectively demote all former members of the aforementioned WRON from the early 1980s to the lowest rank of private, including Hermaszewski. The so-called "degradation act" was met with controversy in Polish and foreign media primarily due to the case of Hermaszewski, who was initially included as a member of the WRON without his consent or knowledge. In the end, the proposed law was vetoed by President Andrzej Duda, who used Hermaszewski's case as one of the reasons why the "degradation act" needs to be rewritten.
