His practice emphasizes complex and multi-party corporate and commercial litigation, commercial class actions, oil & gas litigation including royalty, environmental and CAPL issues, shareholder disputes and professional negligence.
Carsten has represented governments, airlines, major and independent oil and gas firms, and individuals, and he acts for the Alberta Lawyers Insurance Association in defence of professional negligence claims.
Carsten has extensive trial and appellate experience and is frequently retained in conflict matters.
Carsten has significant arbitration and hearing panel experience, both as counsel and as a neutral. For example, in 2012 Carsten served as lead counsel in a complex arbitration proceeding dealing with a price adjustment for environmental costs on the sale of a package of oil and gas assets in Western Canada, with an asserted claim value in excess of $800 million. Carsten is a Fellow of the Chartered Institute of Arbitrators (FCIArb).
During a leave of absence from JSS Barristers from 1998 to 2000, Carsten served as Senior Legal Officer at the United Nations Compensation Commission in Geneva, Switzerland, dealing with claims from the first Persian Gulf war, including Kuwait’s oil loss claim arising from well fires started by departing Iraqi forces. Carsten was responsible for overseeing the quantification of the amount of oil lost, with the assistance of reservoir engineering experts. This claim is possibly the largest single oil and gas loss ever resolved. Subsequently, Carsten was responsible for overseeing development of a consistent method for resolving the thousands of individual business loss claims filed with the UNCC as a result of the war. The methodology which Carsten and his team developed was adopted by the UNCC panel responsible for these claims, and was subsequently applied to thousands of similar claims.
Carsten was lead counsel on the largest securities class action in Canada which settled in 2009, and is presently lead counsel in several other class actions.
