Funeral Mass on Good Friday?

In Paul Turner's Blog by Paul Turner

Q:  Is it allowed to have a Funeral Mass on Good Friday?  Someone told me they do it in in another diocese.   I am just curious, since Good Friday does not have a mass.
God Bless and Thank you,
A:  It is not permitted to have a funeral mass on Good Friday. There may be a funeral without mass.  It’s possible that a priest was unaware of this or thought that the rule did not apply in his case. I just don’t know how to explain it.
