If there is a link that would be appreciated.  I do have an interest in these matters and more factually relevant information always helps.

With regards to available resources, ie. funding for lawsuits, it would depend on where these resources are coming from, I agree.  If funds were specifically earmarked for litigation that is one thing.  If they're using funds earmarked for education/training or building the band's economy that is entirely something else.

To be fair, the timing of this claim is suspicious.  With land values increasing to what they are now I think there is a huge economic incentive for claiming rights.  With that in mind I think they're considering this something of a future investment, so in a way it is being constructive, in a roundabout manner.
