Updated on

Franco-Swiss conductor born in 1942, definitively acquitted in the Order of the Solar Temple case.

Franco-Swiss conductor and composer Michel Tabachnik was associated with teachings of the Order of the Solar Temple and prosecuted after deaths in 1994–1995. He was acquitted at trial in 2001 and on appeal in 2006; the civil parties’ cassation appeals were rejected in 2007. His involvement in doctrinal activities is documented, but criminal responsibility for the deaths was never established.
