The National Hispanic Media Coalition will file suit today to block the Federal Communications Commission’s approval of the sale of Univision Television Network and 13 Spanish-language TV stations to Los Angeles investor A. Jerrold Perenchio.

The FCC last month approved the sale, which will allow Perenchio to own a 75% stake in such stations as KMEX-TV Los Angeles, WLTV-TV Miami, and KDTV-TV San Francisco (Daily Variety Oct.1).

The FCC action is controversial, since it allows Mexico media magnate Emilio Azcarraga back into the U.S. TV business. In the mid-1980s, an FCC judge found that Azcarraga violated a U.S. law that barred foreigners from owning more than a 25% stake in U.S. broadcast properties.

No legal action was taken against Azcarraga, who sold the properties to Hallmark Cards.
