Strictly speaking, I think the only bit that's perjury would be falsely claiming to be the copyright holder (which probably applies in this case, though I suppose the argument could be made that they were just wrong, not lying), which still leaves plenty of room for falsely claiming that something infringes a copyright.

To file a DMCA complaint you must be the copyright holder, or authorized to act on their behalf.

Yes, and it's only that assertion that is made under penalty of perjury, not the assertion that the targeted work actually infringes on that copyright.

So, if they aren't the copyright holder (as in this case) they have committed perjury by asserting they are.

[thfuran]

Possibly not if they thought they had a valid claim, but I really don't know how that would work out in practice.
