De CEO van het Heartland Institute, Joseph Bast, is door een Texaanse rechter neergezet als ongeloofwaardige getuige. Het Heartland Institute is een door het bedrijfsleven gesponsorde denktank, waar de liberale Teldersstichting een deel van z’n recente klimaat- en energievisie op heeft gebaseerd. Uit pagina 335 en 336 van het lijvige feitenrelaas van de Texaanse rechtbank:
Mr. Joseph Bast, president and CEO of the Heartland Institute, testified for the Intervenors regarding the Texas Taxpayers’ Savings Grant Programs (“TTSGP”), a school voucher bill that failed in the 82nd Legislative Session. As a threshold matter, this Court finds that Mr. Bast is not a credible witness and that he did not offer reliable opinions in this matter. While Mr. Bast described himself as an economist, he holds neither undergraduate nor graduate degrees in economics, and the highest level of education he completed was high school. Mr. Bast testified that he is 100% committed to the long-term goal of getting government out of the business of educating its own voting citizens. Further, his use of inflammatory and irresponsible language regarding global warming, and his admission that the long term goal of his advocacy of vouchers is to dismantle the “socialist” public education system further undermine his credibility with this Court.
