Austria has been a member of the 20-nation body since 1959, but plans to leave because membership ties up around 70 percent of its budget for funding such international research, Science Minister Johannes Hahn said late Thursday.
"In the meantime there have been diverse research projects in the European Union which offer a very large number of different scientists' perspectives," Hahn said in a statement.
Austria contributes 2.2 percent of CERN's budget. It will be the first country to leave the organization since Spain's departure in 1969. Spain rejoined in 1983.
