The Valeant/Allergan takeover attempt just got uglier. William Ackman’s Pershing Square Capital Management has filed a lawsuit against Allergan in the Delaware Court of Chancery seeking confirmation that calling a special meeting of shareholders will not trigger Allergan’s recently adopted poison pill. In its announcement, the activist hedge fund firm, which has teamed up with Valeant Pharmaceuticals to make an unsolicited takeover offer for the Botox maker, is concerned that under Allergan’s bylaws the special meeting, designed to change the board’s directors, may trigger the pill and dilute its stake.

Pershing Square owns nearly 10 percent of Allergan and under Allergan’s by-laws at least 25 percent of shareholders must call for the special meeting. The pill would be triggered if a shareholder or group of investors acquired more than 10 percent of the stock. Ackman says he has asked Allergan for clarification on this issue but has not received a response. “We regret that we were forced to file this lawsuit,” Ackman states in a press release, calling Allergan’s non-response “a blatant attempt to frustrate shareholders’ ability to express their views and exercise their rights.”
