J1427+2632 is a double-lobed giant radio source (GRS) whose projected linear size is 1.2 Mpc. As seen in the FIRST image of this object, its structure is as follows. A compact core identified with a QSO is straddled by two lobes of which the north-eastern one is weak, diffuse, and devoid of a hotspot. The north- eastern lobe is thus a clear-cut case of a relic. Its appearance is an irrefutable evidence that the activity of the nucleus of J1427+2632 ceased once in the past and both of the lobes have not been fuelled since then. If the apparent hotspot in the south-western lobe is actually an unrelated compact source, then the GRS would no longer remain an asymmetric FR II-like but instead a core-dominant triple (CDT). To provide support for this scenario, a core-jet or a compact double morphology of this feature seen with C-band EVN observaitons, particularly if its P.A. and the P.A. of the GRS are different, would demonstrate that the feature is not a hotspot of the lobe of the GRS but a separate source,
