I would guess that the line "...thereby supporting all Congressional efforts to ensure that Congress enacts the required joint resolution on or before October 1, 2005 to inactivate Title. " is refering to Title III of the Patriot Act, which is referanced earlier in the sentence. It appears that the City Council resolution is urging that Baltimore's congresspeople push for the passing of a resolution in the U.S. Congress that would ensure that Title III of the Patriot Act sunsets when it is supposed to (ie, Oct. 1, 2005).

Just my guesswork.
