[5] De Magistris appeared before the CSM (the governing board of the magistracy) in January 2008 to defend himself against the serious allegations of the Minister and his inspectors.

[8] In 2021, he announced he would run as president of Calabria in the upcoming snap regional election to replace the late Jole Santelli.

While in Catanzaro, he worked for several years on the "Poseidone" investigation into misuse by politicians of European Community subsidies for sewage filter systems and other business projects in Calabria.

Luigi de Magistris has been removed from the investigation with the accusation that de Magistris did not keep the details of the case confidential and revealed the names of people under investigation, including Forza Italia senator Giancarlo Pittelli and general Walter Lombardo Cretella.

[10] In April 2018, de Magistris wrote to the head of the Naples port authority, Rear Admiral Arturo Faraone, expressing his displeasure with the presence of USS John Warner (SSN-785) near his city.

He called Naples a "City of Peace" that respects "the fundamental rights of everyone, convinced of disarmament and international cooperation," according to the Italian newspaper La Repubblica.
