Confusion Amidst Sovereign Immunity - Article 300 vs. 19(1)(g)

I've been going crazy with the reading on sovereign immunity in our Constitution classes. Specifically, this thing with Article 300 and 19(1)(g) is totally confusing me. Article 300 basically says that a president or governor can't be sued for official acts without their consent, while on the other hand, 19(1)(g) says that every citizen has the right to move to court for the enforcement of any of the rights conferred by this Part. Which means essentially, citizens have the right to take their government to court for violating their rights. But how does this right apply to government officials who have sovereign immunity? Is the right to move to court just a theoretical concept here? Please clarify, someone.
