Isn’t it a false testimony?
No, because it’s not actually testimony — and the lav is on testifying falsely.
The Chasam Sofer held that a person who does not follow shamita should not be עולה when it is being leined on Yom Tov.
And I’m sure a thief should not be called up when we lain “Lo Tignovu.” But so what? What does that have to do with anything? Laining isn’t testimony either.
We have a minhag according to the Chok Yaakov for those who wear Tefillin to keep it on the first day of Chol Hamoed when leining kadesh.
And? So what? It’s a nice minhag, but I fail to see how that has any relevance here. If your ba’al kriah doesn’t have the custom to wear tefillin on Chol HaMoed, he can still lain, no?
