No one, it appears, has thought of the law of unintentional circumstances. The Charedim (ultra-Orthodox) are very quick to declare boycotts against supermarkets and other businesses they don't like. Perhaps these businesses will use the law against them.
Then there's the possibility that somebody might sue Safed Rabbi Shmuel Eliyahu and the 300 other rabbis, many on govt payroll, who are behind an ongoing boycott by Jewish property owners against non-Jews (mainly Israeli Arabs, foreign workers and African refugees) who want to rent or buy from them?

Every cloud has a a silver lining...

And then there's Ben Caspit, in Maariv, a regular Israeli. He is, to coin a phrase, fair and balanced, and he wrote this about the Anti-Boycott (Apartheid) Act 2011.
And now the ADL (another craven organisation, perhaps?) is against it.

Knesset Anti-Boycott Law May Infringe On Basic Democratic Rights

Jerusalem, July 12, 2011 … The Anti-Defamation League (ADL) today expressed concern about a law passed in the Israeli parliament which imposes legal liability for damages against anyone calling for a boycott of Israel, including economic, academic, cultural, and other blacklisting.

The law enables Israeli citizens to bring civil suits against people or organizations instigating anti-Israel boycotts, and bars companies which participate in any boycott, including of goods produced in the West Bank, from bidding for Israeli government tenders.

Abraham H. Foxman, ADL National Director, who is currently in Israel, issued the following statement:
The Anti-Defamation League has a long history of vigorous opposition to any and all boycotts of Israel, and works every day to expose and combat those who seek to cause damage to the Jewish state. We are, however, concerned that this law may unduly impinge on the basic democratic rights of Israelis to freedom of speech and freedom of expression.

Among Israel's many assets is its vibrant democracy – a fact clearly supported by the six-plus hour debate of this bill in the Knesset. To legally stifle calls to action – however abhorrent and detrimental they might be – is a disservice to Israeli society. We hope Israel's Supreme Court will quickly take up a review of this law and resolve the concerns it raises.
