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.
