Taro Pharmaceutical Industries Ltd. (TAROF) is suing Sun Pharmaceutical Industries Ltd. (524715.BY) due to a number of allegations that Sun failed to disclose shareholder material information in its pursuit to acquire Taro.

There has been a two-year standoff between Mumbai-based Sun and Israel-based Taro since Sun originally struck a deal to buy its ailing peer in 2007 at $7.75 a share. But an equity infusion from Sun, as part of the agreement, boosted Taro. With its stock trading above the offer, the company isn't as keen on the original deal.

On Tuesday, Taro said Sun failed to disclose recent action by the U.S. Food and Drug Administration against its majority-owned U.S. subsidiary Caraco Pharmaceutical Laboratories Ltd. (CPD) in which the FDA seized $20 million in products, effectively closing down the U.S. unit's manufacturing operations. The FDA said it found manufacturing defects at Caraco's plants, including oversized tablets.

Taro alleges the FDA's action grew out of a "long pattern of failure to comply with regulatory requirements." It cited the impact of the events as harmful to Taro if Sun were to gain control of the company.

Taro said Sun illegally used confidential information to disrupt and harm Taro's customer relations and undermine Taro's revenue.

Taro is seeking to prohibit use of Sun's "improper tender offer materials" as well as seeking damages and injunctive relief.

The U.S. District Court filing in New York on Tuesday is in addition to ongoing pending litigation involving Taro, Sun and others in Israel and New York state courts.

Sun officials in India weren't immediately available to comment.

Taro's shares were down 1.6% to $9 in after-hours trading.
