Recent and on-going efforts by individual or groups of states aim to organize parliamentary mechanisms and substantive issues concerning space law. The article addresses organizational matters of the Legal Subcommittee (LSC) of the UN Committee on the Peaceful Uses of Outer Space (COPUOS) and particularly the debate between procedure and substance. The article enquires whether amending the parliamentary process can be expected to yield results in the absence of agreement to proceed on substantive matters. Whilst highlighting the achievements of COPUOS and its LSC in the progressive development and codification of space law, attention is paid to salient decisions concerning organizational matters, taken with respect to the COPUOS and its LSC spanning the period 1990 to 1999 and post 1999 to present. Analysis is undertaken of reasons for presumed decline, alongside current and future perspectives that shall influence COPUOS and its LSC in their respective law making functions.
