MEMORANDUM OPINION AND ORDER Four cities and the country’s largest gun violence prevention organization have brought this action under the Administrative Procedure Act, challenging an interpretive rule and three determination letters issued by the Bureau of Alcohol, Tobacco, Firearms and Explosives (the “ATF”), and the ATF’s failure to respond to their petition for rulemaking. Two individuals, and BlackHawk Manufacturing Group, Inc., d/b/a 80 percent Arms, and Firearms Policy Coalition, Inc. (the “Proposed Intervenors”) move to intervene as defendants. Because the Proposed Intervenors have not carried their burden to show that the defendants in this action do not adequately represent their interests, they may not intervene as of right.

Therefore, the Proposed Intervenors’ motion is DENIED. I.
