Early life and education 
Soeharno was born in 1977 in The Hague and is of Indonesian descent. He completed his secondary education on gymnasium level and did not start his higher education for another two years. During this period, he traveled through the United States, where he did volunteer work and served as a bassist in a band. Between 1997 and 2003, Soeharno studied theology at Utrecht University followed by five years of legal theory. He simultaneously studied philosophy at Radboud University Nijmegen and the University of Münster in the years 2000–05. He obtained his doctorate in legal theory from Utrecht University in 2009 after finishing his dissertation titled The Integrity of the Judge: A Philosophical Inquiry. Soeharno was also a visiting scholar at the University of Cambridge's Pembroke College in 2006.

Career 
He started working as a lawyer for De Brauw Blackstone Westbroek in Amsterdam in 2008. He initially worked for its finance department, but his focus later shifted to integrity, ESG, human rights, and disciplinary and governance matters. Soeharno also started teaching ethics, judgement, and disciplinary law at the Training and Study Centre for the Judiciary (SSR) the following year, he became a judicial integrity research fellow at Utrecht University's Montaigne Centre for Rule of Law and Administration of Justice, and he served as an editor of the Netherlands Journal of Legal Philosophy. In 2012, he became a professor at the University of Amsterdam. His specialty is administration of justice and legal philosophy, and he devoted his inaugural speech to the renewed interest in oaths. Soeharno remained active as a lawyer and as a teacher for the SSR, and he would later also take a job as deputy judge at the commerce chamber of the Court of Appeal of 's-Hertogenbosch. At the university, he started serving on the scientific integrity committee in 2013, and he was program director of its Honours College of Law from 2015 to 2021. During a conference, he pled for the involvement of theologians in the drafting of new legislation, as it could lead to more just laws.

Soeharno participated in the 2019 Senate election as the tenth candidate of the CDA. He was not elected, as his party won nine seats. Following the stepping down of Senator Ben Knapen in 2021 to serve as Minister of Foreign Affairs, Soeharno was appointed to the Senate, and he was sworn in on 28 September. He was on the Committee for Economic Affairs and Climate Policy / Agriculture, Nature and Food Quality and the Committee for Social Affairs and Employment. Soeharno remained active in his other positions with the exception of deputy judge. He stepped down as senator after 1 February 2022 to allow for the return of Knapen, whose stint as minister had ended due to the swearing in of the fourth Rutte cabinet. When Minister for Legal Protection Franc Weerwind was proposing reforms of oversight of the legal profession to parliament, Soeharno signed a letter with over twenty others criticizing plans to have a new national regulator operate on behalf of the Netherlands Bar. They argued the body should be independent.

Soeharno ran for re-election to the Senate in 2023. He was placed tenth on the party list, but the CDA received only six seats.
