Hi guys,

I need your assistance by the following problem:

list1 = {{0,A,A,A}, {1,B,B,B}, {0,C,C,C}, {1,D,D,D}, {1,F,F,F},
{0,G,G,G}, {0,H,H,H}}

Every 1st element of the each sublist should be checked. Is the first
element a ZERO, this sublist should be removed from the list. If it is
a ONE - this sublist remains in the list.

In this example the output should be:

{{1,B,B,B}, {1,D,D,D},{1,F,F,F}}

Thanks for your help!
