Papadakis resigned in protest in 1856 when Joseph Mindler (1808–1868) a Bavarian officer of the royal court and stenographer of the Parliament was hired to teach stenography. Mindler was paid a significantly higher salary than Papadakis. The government in response offered to pay Papadakis higher wages. On 10 May 1859 a political incident rocked the university community when the students were involved in a massive protest called the skiadika (σκιαδικά). Several years later in October 1862,
King Otto was exiled to never return to Greece.
Papadakis and the college community continued to flourish. Papadakis became dean of the Philosophical School twice and he also became president of the University of Athens right before his death in the academic year 1876–1877. He wrote for several publications in Greece.
He wrote about his observations of the moons of Jupiter and published it in the Greek paper Logodos (Λογοδος). He also published meteorological observations in local Greek newspapers and was a member of the Greek archeological society.
