I linked to this before, there are updates at the end, including(from Technology.News)
State climate scientist, Michael 'hockey stick' Mann commits contempt
of court in the 'climate science trial of the century.' Prominent
alarmist shockingly defies judge and refuses to surrender data for open
court examination. Only possible outcome: Mann's humiliation, defeat and
likely criminal investigation in the U.S.
Michael Mann, who chose to file what many consider to be a cynical SLAPP (Strategic Lawsuit Against Public Participation) libel suit in the British Columbia Supreme Court, Vancouver six long years ago, has astonished legal experts by refusing to comply with the court direction to hand over all his disputed graph's data. Mann's iconic hockey stick has been relied upon by the UN's IPCC and western governments as crucial evidence for the science of 'man-made global warming.' (snip)
The negative and unresponsive actions of Dr Mann and his lawyer, Roger McConchie, are expected to infuriate the judge and be the signal for the collapse of Mann's multi-million dollar libel suit against Dr Ball. It will be music to the ears of so-called 'climate deniers' like President Donald Trump and his EPA Chief, Scott Pruitt.
Mann's been trying to spin this as no big deal; he's lying.
