Double Foul

[commish]

In 30 years of officiating basketball I have never seen the following situation: Boy's varsity & 3 person crew. In a trasition brekaway, A20 drives to the basket on the Lead-Trail side of the floor. There is a massive collision with defender B15 as A20 is in the air laying the ball in the basket. Lead had a block and Trail had a chanrge. After consultation, the two officials involved come out with a double foul and wipe off the basket. Can there be a double foul in this situation? How can there be a charge when there was a block? How can there be a block when there was a charge?
