Judicial Opinion 131 Open Access

Abstract

Opinion 131 addresses a Request for an Opinion asking the Judicial Commission to conserve the genus name Hauser 1885 (Approved Lists 1980) over its earlier homonym, the protozoan genus name Müller 1786. The Judicial Commission agrees that the later homonym is illegitimate and that the replacement of the prokaryotic name would be undesirable. It is also concluded that Müller 1786 is an objectively invalid name under the . Judicial Opinions 9, 12 and 130 serve as precedents for the conservation of Hauser 1885 (Approved Lists 1980) over Müller 1786. This action is taken here and makes the prokaryotic name legitimate.
