Japanese to English Law/Patents Law: Contract(s)

From an agreement on the terms of use of financial analysis information, which is provided by "Company A" to "Users".

(１)利用者に、本規約に違反する行為があった場合、又は本分析内容を第三者に漏らす等の不正若しくは違法な行為によってA社に何らかの紛議が発生し、これによってA社が損害を被った場合は、A社は当該利用者に対して損害賠償の請求ができるものとします。

The Koujien says 「もつれた議論」for 紛議, and I found one place on the Internet that gave "dissension" as a translation for 紛議, but that doesn't really make sense in this context.

Does anyone have a good translation for this phrase?

Thanks.
