Untenable on its own terms means that it contradicts itself. The conclusion contradicts the premises. For example, "The restaurant opens at five o'clock and it begins serving between four and nine." In this case, I would say that it is the principle that you can get food served before the store opens is untenable on its own terms.

Interested!
