Can we sue?

So one of the labs responsible for testing seed coming into New Zealand for GE material turns out to have not been reporting levels it considered "too small to confirm" - despite being told that we had a "zero-tolerance" regime in place. As a result, the government is going to have to spend a lot of money finding out where the seed was planted, whether its still there, and possibly checking surrounding areas for evidence of cross-pollination.

I really hope we can sue them for their laxity.
