Since you're not agregating data, can't you use a select distinct instead?

SELECT  distinct GCP.id, GCP.Name
FROM Gov_Capital_Project GCP, {?something missing here?}
WHERE TLM.TLI_ID = $2
ORDER BY gcp.name;

(BTW, I wasn't clear if the where clause trying to join to another table?)

Doesn't answer your original question, but hope it helps anyway.
