Based on two alpha-particle chains the Joint Working Party (JWP) Reportassigns the priority for discovering element 112 to work done in 1996 and 2002at GSI, Darmstadt. By doing this it ignores the data presented to the JWP aboutthe discovery of this element already back in 1971 by Marinov et al. In thosemeasurements about one hundred fission fragments were observed from two Hgsources separated from two W targets irradiated with 24 GeV protons.Furthermore, the masses of the fissioning species were measured and interpretedas being due to the atom and four different molecules of element 112 withatomic mass number 272-273. By ignoring these data the JWP disregards the factsthat mass measurement is considered by the Transfermium Working Group (TWG)report as an "excellent criterion" and that "chemical methods can yieldexcellent assignment criteria". It is shown below that all the arguments givenby the JWP attempting to justify their decision are refutable. In particular,their refusal to accept the possibility of the existence of long-lived isomericstates as a consistent interpretation of the data is unjustified, since, amongother observations, evidence has been found recently for the existence of suchstates in naturally-occurring neutron deficient 211,213,217,218Th isotopes, andin the superheavy element region, at atomic mass numbers A = 261 and A = 265(most probably 261Rg and 265Rg), and at A = 292, Z =~122 (eka-Th), withhalf-lives t1/2 >= 10^8 y.
