Mexico's private employers federation has gone to court seeking to force authorities to open highways and rail lines that have been hit by weeks of blockades by protesters.

The leader of the business chamber says 11 weeks of blockades have hurt businesses and threaten to slow the nation's economy. Gustavo de Hoyos said Tuesday the legal appeal argues that the blockades violate the rights of business owners and citizens to work and travel freely.

Radical teachers groups have been protesting mandatory teacher evaluation for months, but have recently taken to blockading railway lines as well as highways.

De Hoyos says Mexico's steel industry has been hit particularly hard and could suffer temporary plant closings.
