Vermont Law School sued as it wants to cover up slave mural

Vermont Law School is being sued to prevent it covering up a painting, depicting the Underground Railway and slaves.  The Law School commissioned with work in 1994.  The artist is fighting for the integrity of the art work.  The case concerns moral rights.

The centre of the case is the Visual Artists Rights Act.  Or is the case really about changing community standards? 

A local paper has this story about the case.  An earlier newspaper article.  It is hard to determine who is morally right.
