"社長に議長に田中氏を任命された” is ambiguous?


> 社長に議長に田中氏が任命された。

i think the possible meanings are:

>   1. Mr. Tanaka was appointed by the chairman to be the president.
>   2. Mr. Tanaka was appointed by the president to be the chairman.
>

Is that all correct?

Using the idea in this thread [The grammar of “虎から食べられた” and
“虎に食べられた”?](https://japanese.stackexchange.com/questions/26199/the-grammar-
of-%E8%99%8E%E3%81%8B%E3%82%89%E9%A3%9F%E3%81%B9%E3%82%89%E3%82%8C%E3%81%9F-and-%E8%99%8E%E3%81%AB%E9%A3%9F%E3%81%B9%E3%82%89%E3%82%8C%E3%81%9F)
is maybe this a possible remedy:

> 社長 **から** 議長に田中氏を任命された。

making it unambiguous and meaning

> Mr. Tanaka was appointed to be the chairman by the president.

Does changing " **に** " to " **から** " both sound natural and remove ambiguity?




Yes, you're right. 社長から議長に田中氏を任命された is a solution to get rid of ambiguity.
