  We report the independent experimental confirmation of an isomeric state in
the proton drip-line nucleus $^{26}$P. The ${\gamma}$-ray energy and half-life
determined are 164.4 $\pm$ 0.3 (sys) $\pm$ 0.2 (stat) keV and 104 $\pm$ 14 ns,
respectively, which are in agreement with the previously reported values. These
values are used to set a semi-empirical limit on the proton separation energy
of $^{26}$P, with the conclusion that it can be bound or unbound.
