Bar of relief by suit under section 9 is provided by:

Section 9 of the Specific Relief Act, 1877, deals with suits for possession of immovable property. The "bar of relief by suit" refers to the finality of certain orders under this section. The correct answer is Act I of 1877 (C).

• Act I of 1877 refers to the Specific Relief Act, 1877. Section 9 of this Act explicitly states that no appeal lies from any order or decree passed in any suit instituted under this section, nor shall any review of any such order or decree be allowed, thus barring further relief by suit on the same grounds.
• Options (A) Act I of 1977, (B) Act II of 1877, and (D) Act II of 1977 are incorrect as they do not correspond to the Specific Relief Act, 1877.
