There's a peculiar copyright case for the governmental works from Philippines.
Apparently, they are at the same time in the Public Domain and under a Non-Commercial/Permission license, or at least the current template claims so:
"this work is only available in the public domain under a non-commercial and permission-based license"
Also, it claims that the images should be used "in accordance with Wikipedia's fair use policy", but none of the 500+ images have any fair-use rationale...
