I own a company where I am the 51% owner, CEO/President and Chairman of the Board.
I have 4 partners owning the 20%, 10%, 10%, 5% and 4% is open stock.

Do I have the authority and power to dissolve the company?

Hello c:

The way you ask indicates that there's a feud going on. If that's the case, you have a fiduciary duty to your stockholders NOT to lose their money.

IF, on the other hand, the company is broke and you're not closing to spite anyone, you certainly can.
