To be perfectly honest, it seems that the only thing a significant number of the French court cases have done is allow the SNPL to make slanderous accusations in the press against Airbus and the BEA. Generally, I think bringing the legal system into it without clear evidence of criminal wrongdoing seems to make things worse rather than better - though there are exceptions (the Royal Commission into the crash of TE901 into Mt. Erebus being a good example).
