A `converse' to the Constraint Lemma

The main result is a direct proof of the implication $(LVKF_{k,3})\Rightarrow( LT_{3k-1,3})$ below. Consider the following statements: ($LVKF_{1,3}$) From any 11 points in $\mathbb{R}^{3}$ one can choose 3 pairwise disjoint triples whose convex hulls have a common point. ($LVKF_{k,3}$) From any $6k + 5$ points in $\mathbb{R}^{3k}$ one can choose 3 pairwise disjoint sets each containing $2k + 1$ points and whose convex hulls have a common point. ($LT_{2,3}$) Any 7 points in $\mathbb{R}^{2}$ can be decomposed into 3 subsets whose convex hulls have a common point. ($LT_{d,3}$) Any $2d+3$ points in $\mathbb{R}^d$ can be decomposed into 3 subsets whose convex hulls have a common point. This statements are true, but the meaning of the article is the direct derivation of one statement from another.
