obstructionist
One who stalls
An obstructionist deliberately impedes or delays progress, especially in legislative or bureaucratic contexts.
The term carries disapproval—it implies someone isn't just opposed to a measure but is actively blocking it through procedural tactics rather than substantive argument: Republicans accused Democrats of obstructionist tactics on the judicial nominations.
As an adjective, it describes such behavior: obstructionist policies.
