[1] Through his legal and political career, he is noted for his hard-line stance regarding officials from the former communist Czechoslovak regime, as well as crimes committed during this period.

[2][3] In May 2012, in the aftermath of the electoral defeat of the Radičová cabinet, Lipšic together with Jana Žitňanská and Gabor Grendel, left the KDH and formed a new political party called NOVA (Slovak: Nová väčšina – Dohoda).

[11] In 1999, he was appointed as Head of the Legal Office at the Ministry of Justice by then Minister Jan Carnogursky, where he was tasked with documenting and investigating crimes from the former Czechoslovak communist regime, which contained over 70.0000 individual cases.

Specifically he targeted former hardline communist leader Vasiľ Biľak, who was accused of signing the official document "inviting" soviet forces to invade.

[13] He was also tasked with authoring laws, enabling the government to effectively combat organized crime,[14] as well as legislation introducing stiffer penalties for violent criminals, including a Three-strikes law system which will send people convicted of three violent crimes to jail for life without parole.

"[15] In addition, Lipšic authored anti-corruption legislation which gave tougher penalties on graft and outlawed bribery for the first time in Slovakia.

Lipšic, a member of the ruling coalition Christian Democrats (KDH), chose to remain with the party, and resigned.

As chairman of the CDY, he was also present at the 6th National Congress of the Christian Democratic Movement (KDH), which took place on 23–24 October 1993 in Ruzomberok.

During his reign, the District Court of Bratislava 1 issued a preliminary measure declaring that the railway strike in February 2003 was illegal and needed to be ended immediately.

Continuing anti-communist policies of his predecessor, Lipsic unsuccessfully attempted to introduce a law, banning Judges who had worked under the former communist regime from the judiciary.

[19] This political move KDH was associated with disapproval of the draft contract between the Slovak Republic and the Holy See regarding the right to objection of conscience, which concerns the armed forces, health, education and training, legal services and labor relations.

[26] On 19 September 2016, while driving home from work through the Bratislava III neighborhood, his Skoda Superb struck a 72- year old pedestrian crossing the street.
