"Emergency" is obviously in reference to an emergency causing the person to miss the meeting (examples: a car accident on the way to the meeting; a canceled flight that would otherwise have been on time; a fire at their domicile that morning). "I didn't read the documentation thoroughly" is regrettable, but not an emergency. Whether it is grounds for kicking the person out depends on the importance of the missed meeting (seemingly extremely), the due diligence of the organization (it seems this was the first person to miss the meeting under rules that have been in effect for months), and the cost of missing it for both parties (under no circumstances is it a "hole in people's live"; they are not sending people who miss the meeting to prison).
