文法句型

obstruct + noun phrase (investigation/process/effort/justice)

用法筆記

Object is typically an abstract noun describing a formal process — investigation, inquiry, vote, negotiation, progress. This sense carries a negative judgment: the obstruction is seen as wrong or unlawful, especially in legal contexts (obstructing justice is a criminal offence). Distinguish from sense 1, which is about physical barriers: sense 2 is about deliberate interference with procedures.
