A delay has been granted in the case of former Massey Energy shareholders who say the coal operator had lied to them about its safety record to inflate stock prices.
Federal prosecutors wanted to protect their criminal probe of the 2010 Upper Big Branch mine disaster by withholding evidence that could help the investors' lawsuit.

She also canceled a scheduling conference set for Thursday.
