For the first time that I’m aware of, the Diocese of Niagara has included the cost of suing ANiC parishes in a financial statement.
You can find the statement here and the relevant line shows that in 2009 the diocese, while not preoccupied with distributing free hugs, spent $395,895 on lawsuits:
Where did this money come from? It wasn’t budgeted – and it still isn’t. It presumably came from the diocese’s primary source of income: the diocesan assessment. That means that with a total assessment in 2009 of $3,044,139, 13 cents out of every dollar contributed by Diocese of Niagara parishioners was used to sue fellow Christians.
The financial statement goes on to declare that the diocese was the defendant in the 2009 legal action; it was actually the plaintiff – the instigator of the suit – as can be seen here. In addition, even if the diocese does finally win all the litigation, it will not recover its legal costs; of the $395,895, only around $80,000 of was recovered.
