It's a very bad Eng sentence in the way it juxtaposes two meaning of 'ground'!

The second part is clear - 'motivo para una demanda'

The first part, if literally referring to 'ground' as in 'land' - las condiciónes/el estado del terreno/suelo'

However, I would tend to go for a more metaphoric interpretation of 'ground conditions', because it's plural. My interpretation is that someone is asking if ignorance of 'ground conditions' is a potential basis for a claim. In which case - 'desconocimientos sobre las condiciones basicas/preliminares/subyacentes etc'

However the more I think about it, the more it comes to me that we often refer to ground conditions' WRT flying aeroplanes specifically, in which case it would be 'condiciones en tierra'.

Yes, a bit more context would be useful!
