Can i sue a NY 49% business corporation owner for selling my full business assets while i was on maternity leave and when i own 51% of the corporation

I am a 51% owner of a New York domestic business corporation where I bout my 51% shares 1 year ago. My 49% business partner sold the full business while I was on maternity leave 5 months ago without my signature or any form of consent. As I found out 3 months ago he offered to pay me back my investment but have been delaying since then. I came to find recently that he sold over $350,000 worth of equipment, inventory and the 10-year lease to several of his contacts that paid mostly in cash and without contracts to avoid taxes. He has been in New York over 20 years and claims to know the law stating that I cannot take any action against him; he has several other private and business ownerships and has no interest in my lost business. Can I sue him for such unlawful sale and do I have the right to ask for my investment back?
