The Spanish press is reporting that after the plane was delayed (it was expected to land in the Canary Islands) they had to confirm the permission, and it was granted as expected.
The Spanish foreign ministry said they never denied landing or requested to inspect the plane (in Spanish soil).
Apparently the Spanish ambassador asked Evo Morales to allow the Austrian police to inspect the plane, and he finally did.
No, Morales landed in the (Spanish-controlled) Canary Islands to refuel after he was denied access to France, et al.
The quote from Morales in this article may be part of the source for the confusion, but as you say the Spanish press reports there was some delay, and I imagine Morales was pretty upset already. His quote seems to be lumping Spain in with the others.
What's your source for the Spanish press, if I may ask?
I realize that I'm not citing any great sources for what happened in Spain, I'm working on it...
EDIT: according to the foreign ministry, Evo Morales was granted permission for a refuel stop in the Canary Islands on Tuesday and if that had to be reviewed and delayed until Wednesday was because other EU countries didn't authorise the plane to enter their aerial space.

All this thing is confusing, indeed.
