```

    ただしい じょうほう にもとづいて はっぴょう しなくてはならない
    
```

I understand that `てはならない` means 'must not/should not'.  
However,I cannot make any sense out of the above sentence that I read in a
book.  
Would appreciate if someone could assist with the meaning.

Meaning of てはならない
Quite simply,

> 「～～してはならない」 = "You must not ~~."
>
> 「～～しなくてはならない」 = "You must ~~."

「ただしいじょうほうにもとづいてはっぴょうしなくてはならない。」 means:

"One must make a/the presentation based on correct information."
