Australia’s largest healthcare company CSL Ltd (ASX:CSL) has had another hospital network join a multibillion-dollar lawsuit against the biopharmaceutical company, according to The Age.

The paper says that Beth Israel Medical Centre, St Luke’s and Roosevelt Hospital have joined a class action, claiming that CSL is involved in price fixing for its blood plasma products.

Driving down supply, inflating prices and eliminating competition are also part of the claims against CSL, says The Age.

CSL reportedly refutes the claims and states that it intends to defend the civil action.

The Age says that the last group to join the mounting lawsuit against blood plasma company CSL, is its main North American competitor, Baxter International.

CSL reported a profit of $1.14 billion for the year ending 30 June 2009.
