Florida-based clothing firm Perry Ellis International Inc is being sued by a union representing around 100 of its workers amid claims the company is improperly withholding its shareholders list.

The Union of Needletrades, Industrial and Textile Employees (UNITE) issued a statement on Monday saying it sued the company in Miami-Dade County court last week after its request for a shareholder list was refused.

It added it union wants the list to communicate to shareholders its opposition to anti-takeover proposals it said management will put to a vote at an annual meeting expected in May.

UNITE said an initial court hearing is scheduled for April 24.
