MALDEF getting "moral support" from Mexico

The earlier post "Mexico may ask international courts to block Proposition 200" discussed Mexico's latest plans to interfere in our laws. Mexico's Foreign Secretary said "We are seeking all the legal opportunities that exist, first using the legal capacities of the United States itself" as well as a couple other prime things.

His statement prompted me to ask whether they're involved in MALDEF's various suits against Prop. 200, and the AZ Republic got out their teaspoon and did a little digging. From "Mexico threatens to take Prop 200 to court":

...The Mexican government has provided "moral support" but has not contributed any money to the legal challenge filed by the Mexican-American Legal Defense and Education Fund, said Danny Ortega, a Phoenix attorney who is helping the group with the lawsuit...

The rest of the article has a quote from Mexico's foreign ministry confirming their Foreign Secretary's statement and discussing how Mexico appealing to an international court might be a futile gesture. (On the plus side, perhaps they might eventually be declared a vexatious litigant.)

Once again, it would be nice if someone would look into this. Has Mexico given something beyond "moral support" to any of the groups trying to challenge Prop. 200? Based on the case of Pedro Marin that question isn't as far-fetched as it might seem.
