Rights of 51% stakeholder in a pvt ltd co.

Hi,

I own 51% stakes to a private Ltd Co. & other director owns 49% stakes. Unfortunately the other director hardly takes interest in the day to day operations & seems to be least interested. I would like to know my rights against the minority share holder, 1. Whether I can buy back shares from him without his consent. 2.  Whether I can transfer his shares to an interested investor at the said share value.

Also let me know if there are any additional rights excluding the above queries.

Thanks.
